New White Paper from Arnold Magnetics: Magnetization Losses in Rare Earth Permanent Magnets
This White Paper from Arnold Magnetics describes the magnetization losses that are possible in SmCo and NdFeB permanent magnet materials. Reversible losses are first discussed followed by irreversible losses, which can be caused by temperature, external fields or radiation. Losses over time by magnetic viscosity are also discussed. Finally, permanent losses caused by corrosion, hydrogen, high temperatures and radiation are considered.
