Abstract
An electronic circuit for demagnetizing ferromagnetic material includes a voltage source and a conductor loop connected thereto, a demagnetizing resonant circuit is arranged in the conductor loop for forming a decaying alternating magnetic field. In the conductor loop, a resonant circuit battery switch is arranged in series with the demagnetizing resonant circuit, and a recharge resonant circuit for pulsed recharging of a charging current into the demagnetizing resonant circuit is arranged in parallel with the demagnetizing resonant circuit and with the resonant circuit battery switch. A recharge store which is arranged in parallel with the voltage source, with the recharge resonant circuit and with the demagnetizing resonant circuit, as well as a recharge switch for interrupting a charging current from the recharge store are located in the conductor loop. The circuit can be operated by a controller for controlling the voltage source and all switches.
