Magnetic field brake device

A magnetic field brake device belongs to machinery and mainly comprises induction magnetic units and electric conduction magnetic units or magnetic attraction units, wherein the induction magnetic units are used for being fixed to a vehicle chassis, and the electric conduction magnetic units or the magnetic attraction units correspond to the induction magnetic units. Each induction magnetic unit is a coil which is wound by silicon covered wires and provided with a proper number of turns, the coil is connected to a microcomputer control module and a switch arranged below a brake pedal and then is connected to a vehicle battery, and the electric conduction magnetic units or the magnetic attraction units are used for being combined to a driving system end of a vehicle. When the brake pedal is stepped on, the induction magnetic units are conducted to attract or repel with the corresponding electric conduction magnetic units or the corresponding magnetic attraction units, so that resistance load is generated, brak
