A Neodymium magnet starts loosing its magnetic force at 80 degree C.

completely at 312 degree C; novak/feigao/lehner/wanderer/plettenberg/neu all use the Neodymium magnets.

Sintered magnets or segmented magnets are better suited for partial loads. this has something to do with eddy currents. the segments simple respond better to the signal than a larger lump. (it's like with transformers, the thinner the E's and I's are in the transformer, the higher frequency it is capable of handling. (the more efficient the transformer becomes at higher frequencies)
