Abstract
Magnetic viscosity parameters kT/q(= Sv) of sintered and melt spun NdFeB vary with internal field. During initial magnetization of thermally demagnetized specimens significant viscosity occurs with melt spun NdFeB but is negligible with sintered NdFeB. Differences in mechanisms of magnetization account for this behaviour.
