Summary:The invention relates to an electronic circuit (10) for demagnetizing ferromagnetic material by resonance with extended decay time. The device comprises a voltage source (20) and a conductor circuit (30) connected thereto, in which a degaussing oscillation circuit (40) is arranged in order to form an attenuated alternating magnetic field. In addition, an oscillation circuit charging switch (31) connected in series with the degaussing oscillation circuit (40) and a recharging oscillation circuit (50) connected in parallel with the degaussing oscillation circuit (40) and the oscillation circuit charging switch (31) are arranged in the conductor loop (30) for recharging the charging current into the degaussing oscillation circuit (40) in a pulsed manner. In the conductor circuit (30) there is a recharge store (60) arranged in parallel with the voltage source (20), the recharge oscillation circuit (50) and the demagnetization oscillation circuit (40), and a recharge switch (32) for interrupting a charging current
