摘要：
AC magnetic properties of toroidal cores made from six different soft magnetic materials were measured. A solid steel core exhibited the highest remanance, coercivity and core loss as expected whereas a nanocrystalline core had the lowest remanance of the cores tested. Increase in dynamic core loss with frequency in steel particle and iron powder cores was low compared with the other cores but was low in permeability. (C) 2000 Elsevier Science B.V.
