Isotropic means a material has the same properties (mechanical, magnetic, and metallurgical properties) in all (x, y and z) directions.
Anisotropic means that a material has different properties in different directions. Sintered Neodymium magnets are anisotropic, and Bonded Neodymium magnets are isotropic.
Together, these two kinds of Neodymium magnets offer designers many different design options.
Hydrogen Decrepitation is a process step used in the production of Neodymiummagnets to create extremely small grains in the material.
A hysteresis loop shows the relationship between the external magnetizing force and the induced magnetic flux density.
If efficiency, especially efficiency-per-unit volume is the deciding factor, designers often choose Neodymium magnets, which deliver up to 20 times the magnetic field per unit volume compared to ferrite magnets, greatly reducing system size and often causing a cascade effect of size reduction throughout the entire system.
