    • PURPOSE: To obtain a compact-sized and movable curing device by providing two low-frequency magnetic field generators which are compatible with each other mechanically and electronically, have interchangeable auxiliary device or unit and generate a processing signal for intercepting continuously or periodically. CONSTITUTION: This curing device is provided with a control device or a generator 10 comprising different megnetized coils 11 (MINT), 12 (MOYI) and 13 (MAXI), pulsation for forming constant electromagnetic characteristics in the periphery of the magnetized coil 11, and sine. Maximum magnetic field is obtained by the smallest and lightest generator, and on the other hand, in order to obtain various sine and pulsation magnetic field patterns, further they are compatible electrically and mechanically to obtain best characteristics of three processing applicators. The interchangeability can be achieved by the processing coil having the substantially same inductance, the voltage and current value can be also optimized by the decrease in number of coils, and even in the case of use at the maximum power, the overcurrent due to undue rise of temperature can be prevented. Thus, a compact-sized low-frequency curing device can be obtained.
