Crane Magnet

Crane magnets work on electromagnetic principles. When an electric current passes through a coil inside a magnet, it creates a magnetic field. According to Ampere's law, a magnetic field is generated around the energized coil, which can attract ferromagnetic substances such as iron, nickel and cobalt. By controlling the current on and off, you can control the presence or absence of magnetic force, so as to achieve the grasp and release of ferromagnetic materials.
