According to the requirement of the pre-magnetic device during retrieving thin magnetic substances, the paper studied the timed-pulse requirement of pre-magnetic device and characteristics for wiring components, voltage and current of charged and discharged circuitries. It proposed the pre-magnetic device with the high magnetic field intensity, low energy consumption and high cost performance for the first time. Inductances and resistances of real measuring magnet coils were agreed on through analysis for pre-magnetizing mechanism and theoretic calculation. It was proven that the design is reasonable. Then the special feature of magnetic fields for magnet coils was studied and analyzed. It showed that the distribution of magnetic fields according with the magnetization requirement of ferromagnetism substance.The systematic structure of the pre-magnetic device with pulse oscillation was proposed for the first time and the surge waves of RLC circuits are transformed into the oscillation waves so that high magnetic-field intensity is formed. It prolongs the working lives. The device is provided with stable performance, low energy consumption of 0.8 kW power per hour. The research and design for pre-magnetic device is a technological innovation in pre-magnetic device field.
