Microsecond level quick electromagnet

The invention discloses a microsecond level rapid electromagnet, wherein coils are fixedly embedded in cylindrical iron yokes, and an iron core is positioned at the axle center of the coils and can axially move. The electromagnet is characterized in that in a plastic shell, two groups of iron yokes and coils which have the same shape and size are coaxially and oppositely arranged, and are an upper iron yoke, a lower iron yoke, an upper coil and a lower coil respectively, the iron core is positioned in a cavity of the axle center of the two coils, the bottom of the lower iron yoke is provided with a hole, a connecting rod passes through the hole and is connected with the iron core, and the upper coil and the lower coil are connected with the corresponding output end of an electronic control circuit respectively. During the switching, a magnetic field force produced by the opposite coil attracts the iron core to quick act, which overcomes the influence of residual magnetism of the prior electrified electromagne
