Based on the transformer coupling theory, magneto electric detonator is impulse by the energy from electromagnetic induction. Magneto electric detonator is named “ safe detonator” with static resistance, strays resistance, lighting resistance and RF electricity resistance. It only can be initiated under the current of special work frequency generated by special blasting device, and can not be initiated by the electricity for daily or industry use (220V, 380V,50 Hz). Magneto electric detonator is mainly applied in the metal mine with dangers of strays, RF electricity, magnetic field interference and lighting induction etc..
