Abstract The differences between demagnetization fields and depolarization fields were compared. The most fundamental reason is the existence of electric charges but the nonexistence of magnetic charges. For ferroics (ferromagnetics and ferroelectrics), the non-equilibrium thermodynamics of phase transitions was considered and the conclusion remains the same.

讨论：退磁场和去极化场的比较

摘要 比较了退磁场和去极化场的区别。最根本的原因是电荷存在而磁荷不存在。对于铁质材料（铁磁体和铁电体），考虑了相变的非平衡热力学，结论保持不变。
