Scientists simulate magnetization reversal of Nd-Fe-B magnets using large-scale finite element models

NIMS has succeeded in simulating the magnetization reversal of Nd-Fe-B magnets using large-scale finite element models constructed based on tomographic data obtained by electron microscopy. Such simulations have shed light on microstructural features that hinder the coercivity, which quantifies a magnet's resistance to demagnetization in opposing magnetic fields. New tomography-based models are expected to guide toward the development of sustainable permanent magnets with ultimate performance. Green power generation, electric transportation, and other high-tech industries rely heavily on high-performance permanent magnets, among which the Nd-Fe-B magnets are the strongest and most in demand. The coercivity of industrial Nd-Fe-B magnets is far below its physical limit up to now. To resolve this issue, micromagnetic simulations on realistic models of the magnets can be employed.

How Does Air Gap Affect Magnet Selection?

How Does Air Gap Affect Magnet Selection? When selecting a magnet for a specific application, understanding the concept of air gap is crucial. An air gap refers to any non-magnetic material that separates a magnet from the ferromagnetic object it is intended to attract. This separation can significantly impact the performance of the magnet, primarily by affecting its holding force. 1. Definition…

"Magnetic levitation is already employed in systems such as Maglev trains, flywheels and high-speed machinery. Now researchers at the Technical University of Denmark have given this old technology a fresh twist by explaining how a magnet can be levitated simply by rotating another magnet of a similar size near it. This unusual effect was first demonstrated by an electronics/computer and software engineer, Hamdi Ucar, in 2021, and the TU-Denmark team say it could be exploited in the contactless handling of objects or used to trap and manipulate ferromagnetic microparticles.

There are three main types of magnetic levitation. In the first, known as active magnetic stabilization, a control system supplies the magnetic force required keep the levitating object balanced. The second, termed electrodynamic suspension, is used in Maglev trains. Here, a moving magnet induces a current in a stationary conductor, producing a repulsive force that increases with the speed of the moving magnet. The last category, called spin-stabilized levitation, features a levitating magnet that spins at around 500 revolutions per minute (rpm) and remains stable thanks to the gyroscopic effect.

The new type of levitation involves two magnets. The first, dubbed the “rotor”, is mounted on a motor with its north and south poles oriented perpendicular to its rotation axis and made to rotate at velocities of around 10 000 rpm. In the TU-Denmark team’s experiments, this magnet was spherical, 19 mm in diameter and made from neodymium-iron-boron.

The second magnet – the “floater” – is placed near the rotor, begins to spin automatically, and then moves towards the rotor until it hovers in space a few centimetres below it. The floater precesses with the same frequency as the rotor and its magnetization is oriented close to the axis of rotation and towards the like pole of the rotor magnet. If disturbed, a restoring force moves it back to its equilibrium position.

“It is quite surprising that magnetic levitation develops in such as relatively simple system,” says Rasmus Bjørk, a physicist at TU-Denmark who led the study together with Frederik Laust Durhuus and Joachim Marco Hermansen."

"“It is intuitive to all that the magnetostatic force that one magnet exerts on another can be both attractive and repulsive,” explains Durhuus. “Without rotation, the free magnet will rotate so the force becomes purely attractive and then the magnets will collide into each other. What makes the new magnetic levitation system so special is that the rotation itself allows the floater to remain in a counterintuitive configuration, nearly perpendicular to the rotor’s field, where the magnetostatic force both attracts and repels it.”

Brazil starts to tap its rare earth reserves

A rare earth mining project nearing completion in the midwestern state of Goiás has the potential to kickstart the development of a rare earth industry in Brazil, market participants said

The Mineração Serra Verde project, owned by energy transition-focused private equity firm Denham Capital, is in the final stages of commissioning and is scheduled to launch ionic clay rare earth production by the end of this year.

Planned phase 1 output is large by industry standards, at around 5,000 tonnes per year of rare earth oxides contained in concentrate. Importantly, this will include both the light rare earths neodymium and praseodymium and the heavy rare earths dysprosium and terbium, which are all needed for high-performance neodymium iron boron (NdFeB) magnets for the engines of electric vehicles (EVs).

Neodymium and praseodymium are used in the largest amount in NdFeB magnets, but trace quantities of dysprosium and terbium are critical for maintaining the performance of these magnets at high temperatures inside an EV engine.

Global production of heavy rare earth ores is concentrated in Myanmar, and supply is frequently disrupted. This is accelerating the search for new sources of supply to meet growing demand from the automotive sector.

Magnetoactive liquid-solid phase transitional matter

https://www.cell.com/matter/fulltext/S2590-2385(22)00693-2#articleInformation

Magnetically actuated miniature machines can perform multimodal locomotion and programmable deformations. However, they are either solid magnetic elastomers with limited morphological adaptability or liquid material systems with low mechanical strength. 

Here, we report magnetoactive phase transitional matter (MPTM) composed of magnetic neodymium-iron-boron microparticles embedded in liquid metal. MPTMs can reversibly switch between solid and liquid phase by heating with alternating magnetic field or through ambient cooling. 

In this way, they uniquely combine high mechanical strength (strength, 21.2 MPa; stiffness, 1.98 GPa), high load capacity (able to bear 30 kg), and fast locomotion speed (>1.5 m/s) in the solid phase with excellent morphological adaptability (elongation, splitting, and merging) in the liquid phase. We demonstrate the unique capabilities of MPTMs by showing their dynamic shape reconfigurability by realizing smart soldering machines and universal screws for smart assembly and machines for foreign body removal and drug delivery in a model stomach.

Informative Report on Permanent Magnet Market | Bis Research

A permanent magnet is a material that produces a persistent magnetic field without the need for an external power source. It is magnetized through a process called "magnetization" and retains its magnetic properties over time.

Permanent magnets are typically made from materials such as iron, cobalt, nickel, and alloys like neodymium or samarium-cobalt. These magnets have a north and south pole, and the magnetic field lines emerge from the north pole and curve around to the south pole. The strength of the magnetic field can vary depending on the material and the magnet's size.

The Global Permanent Magnet Market was valued at $329.83 billion in 2023 and is projected to grow at a CAGR of 8.52%, reaching $820.14 billion by 2034

Permanent Magnet Overview

Permanent magnets are materials that generate a constant magnetic field without the need for an external power source. Unlike electromagnets, which require an electric current to produce a magnetic field, permanent magnets maintain their magnetism over time due to the alignment of their atomic magnetic domains. These domains are regions where the magnetic moments of atoms are aligned in the same direction, giving the material its magnetic properties.

Permanent magnets are typically composed of ferromagnetic materials, such as iron, cobalt, nickel, and certain alloys like neodymium (NdFeB) and samarium-cobalt (SmCo), which are known for their strong magnetic properties. The strength of a permanent magnet is influenced by its composition, the size and shape of the magnet, and the method used to magnetize it.

Permanent Magnets Market Analysis, Growth Forecast by Manufacturers, Regions and Application to 2030

In 2023, the global permanent magnets market reached a valuation of USD 22.18 billion and is projected to grow at an 8.7% compound annual growth rate (CAGR) from 2024 through 2030. This growth is largely driven by the increasing demand for renewable energy sources like wind and solar power. Permanent magnets play a critical role in enhancing the efficiency of wind turbine generators, a key application area in this sector. Specifically, rare earth magnets such as Neodymium Ferrite Boron (NdFeB) are commonly used in wind turbines due to their high reliability and reduced maintenance needs.

In the United States, the demand for permanent magnets is anticipated to grow at a faster rate than that for ferrite magnets, driven by applications in high-tech sectors like robotics, wearable technology, electric vehicles (EVs), and wind energy. Following the 2008-09 economic downturn, the U.S. automotive industry has seen steady recovery, with a growing emphasis on electric vehicles. Notably, the adoption of plug-in electric vehicles has increased, spurred by innovations from prominent manufacturers including Tesla, Chevy, Nissan, Ford, Audi, and BMW. For example, Tesla began incorporating motors with neodymium magnets in 2018.

Despite this growth, the U.S. faces a supply challenge due to a limited number of domestic manufacturers for permanent motor magnets, leading to substantial imports. In 2023, the U.S. imported around 4 million pounds of automotive parts from China, a majority of which were electric motors. The ongoing trade tensions with China have raised concerns about access to essential rare earth materials. In response, the U.S. government has launched several initiatives, including funding mining projects under the Defense Production Act, aiming to bolster the domestic supply of rare earth materials and reduce dependence on imports.

The Neodymium-Iron-Boron Ternary System

Phase Poll #10 wrapped up yesterday with the final result as 42.5% Fe, 30% Nd, and 27.5% B. This ternary system is most well known for neodymium-iron-boron magnets, so we’re going to spend a little bit of time discussing those before we narrow in on the chosen composition.

Nd-Fe-B magnets are permanent magnets with the composition of Nd2Fe14B, considered to be an intermetallic, and a tetragonal crystal structure. (Permanent magnets are those materials which are magnetized and create their own magnetic field, such as refrigerator magnets.) These neodymium magnets are the most widely used rare earth magnets and have numerous applications, including in computers, speakers, door locks, electric generators, among countless others. These magnets are typically produced either through powder metallurgy and sintering, or through melt spinning.

The chosen composition results in another stoichiometric, intermetallic phase, NdB4. Its space group is P4/bmb, meaning it crystalizes with a tetragonal crystal structure as well. On their own, there is little interest in neodymium boron compounds in the literature.

Permanent Magnets Market 2030 Overview, Global Industry Size, Price, Future Analysis

In 2023, the global permanent magnets market reached a valuation of USD 22.18 billion and is projected to grow at an 8.7% compound annual growth rate (CAGR) from 2024 through 2030. This growth is largely driven by the increasing demand for renewable energy sources like wind and solar power. Permanent magnets play a critical role in enhancing the efficiency of wind turbine generators, a key application area in this sector. Specifically, rare earth magnets such as Neodymium Ferrite Boron (NdFeB) are commonly used in wind turbines due to their high reliability and reduced maintenance needs.

In the United States, the demand for permanent magnets is anticipated to grow at a faster rate than that for ferrite magnets, driven by applications in high-tech sectors like robotics, wearable technology, electric vehicles (EVs), and wind energy. Following the 2008-09 economic downturn, the U.S. automotive industry has seen steady recovery, with a growing emphasis on electric vehicles. Notably, the adoption of plug-in electric vehicles has increased, spurred by innovations from prominent manufacturers including Tesla, Chevy, Nissan, Ford, Audi, and BMW. For example, Tesla began incorporating motors with neodymium magnets in 2018.

Despite this growth, the U.S. faces a supply challenge due to a limited number of domestic manufacturers for permanent motor magnets, leading to substantial imports. In 2023, the U.S. imported around 4 million pounds of automotive parts from China, a majority of which were electric motors. The ongoing trade tensions with China have raised concerns about access to essential rare earth materials. In response, the U.S. government has launched several initiatives, including funding mining projects under the Defense Production Act, aiming to bolster the domestic supply of rare earth materials and reduce dependence on imports.
