In the pulse magnetic field generator, a power supply device is a central control singlechip, a laser ranging module and an infrared coding module for supplying electric energy.
The central control singlechip is used as a central starting point, and the central control singlechip generates an electric pulse with adjustable frequency and duty ratio to control the switch control circuit; the switch control circuit is connected with the adjustable numerical control power supply module and the energy storage circuit; the energy storage circuit is externally connected with an output control circuit, and the output control circuit is externally connected with a Helmholtz coil; the helmholtz coil is energized to produce a magnetic pulse in space.
