The use of damped electromagnetic waves in pulse magnetic therapy machines has some advantages:

1. **Reduce energy loss:** Damping electromagnetic waves can reduce energy loss, allowing the magnetic therapy machine to more effectively deliver energy to the treatment area and improve the treatment effect.

2. **Reduce side effects:** By precisely controlling the waveform and frequency of damped electromagnetic waves, unnecessary side effects and adverse effects on surrounding tissues can be reduced, and the safety of treatment can be improved.

3. **Enhanced treatment effect:** The characteristics of damped electromagnetic waves enable the intensity and frequency of the magnetic field to be adjusted more accurately, thereby better adapting to different types of diseases and individual differences, and improving the treatment effect.

4. **Broader application scope:** The use of damped electromagnetic waves allows the pulse magnetic therapy machine to be more flexibly applied to different types of diseases and clinical situations, expanding its application scope.

The working principle of damped electromagnetic waves in electromagnetic therapy machines is based on the characteristics of its waveform and the attenuation mechanism of energy.

1. **Waveform characteristics:** Damped electromagnetic wave is an electromagnetic wave whose waveform gradually attenuates. In electromagnetic therapy machines, this waveform is usually generated by a regulating circuit. Through appropriate circuit design and control, the required waveform can be produced.

2. **Energy Attenuation:** One of the characteristics of damped electromagnetic waves is the attenuation of energy. In electromagnetic therapy machines, through the design of the control circuit and parameter settings, the energy of the electromagnetic waves gradually attenuates during the transmission process, thereby achieving more precise therapeutic effects. This energy attenuation avoids overstimulation or damage to tissue while ensuring the treatment area receives the appropriate amount of energy.

3. **Adjust treatment parameters:** The damped electromagnetic waves in the electromagnetic therapy machine can be adjusted according to treatment needs. By adjusting circuit parameters, such as frequency, amplitude, and pulse width, the characteristics of electromagnetic waves can be precisely controlled to meet the treatment needs of different diseases and individuals.
