线圈中通过恒定的电流，使工件通过并远离线圈(一般用输送带)，工件便会失去磁性。耗电较大，长时间工作时线圈会发热，适用于长条而量大的工件

Coil Type magnetizer is a kind of alternating current air core coil, When magnetizing current field is generated inside the air core.

If you put in and out the magnetized work into the magnetic field, the regular magnetic aligned work is vibrated and magnetic domain becomes differential direction then the work is demagnetized.

应用场合：
广泛应用于机械制造、轴承、液压件、冲压件、五金工具制品、模具制造等需要消磁的行业
