2.1 Early Permanent Magnets. Magnet development has its origins in lodestones, which are magnetic rocks that consist of the iron-oxide mineral magnetite (Fe 3 O 4).These naturally derived magnets are found in many places on the Earth''s surface and were initially employed to attract metallic iron ore, which became available around 1200

The REPM are metal magnets. Their magnetic components are alloys of 3d-transition metals (TM) with elements of the rare-earth group (RE or R), i.e. the 4f-elements La (57) through Lu (71) and Y (39). The RE in fig. 1 are used in magnets with Co as the main constituent.

The performance of permanent magnets is estimated based on the magnetization (M) and maximum energy product and the magnetic parameter such as (BH) max, spontaneous magnetization and coercive forces

Permanent magnet quadrupoles (PMQs) are an alternative to common electromagnetic quadrupoles especially for fixed rigidity beam transport scenarios at particle accelerators. Using those magnets for experimental setups can result in certain scenarios, in which a PMQ itself may be exposed to a large amount of primary and secondary particles with

The rare earths are of a group of 17 chemical elements, several of which are critical for the energy transition. Neodymium, praseodymium, dysprosium and terbium are key to the production of the permanent magnets used in electric vehicles (EVs) and wind turbines. Neodymium is the most important in volume terms.

Rare earth elements (REEs), which comprise of only 17 elements from the entire periodic table, play a critical role to our national security, energy independence, environmental future, and economic growth. Many advanced technologies have components made from REEs such as magnets, batteries, phosphors, and catalysts.
