An electromagnet is a low-voltage electric apparatus for converting electrical energy to mechanical energy, and is widely used in industrial fields and various products. An electromagne is magnetized by a current-carrying coil round it, and can produce much larger magnetic field than permanent magnets. An electromagnet has a stator core on which a wire coil is wound, and a movable core faced with the stator core via a gap. When the exciting coil of its excitation system is powered to form a magnetic field incorporating with the iron core, the magnetic field attraction force attracts the armature with mechanical load towards the coil and the iron core so that the electromagnet starts to work. The magnetic field disappears when the current ceases. Electromagnets have a wide range of application. Such magnets are widely used in industrial installations and automated systems. Electromagnets are employed in automatic transmissions of vehicles. The electromagnet is used in the steel industry for material handling purposes. A release electromagnet is used to constrain or release a movable member such as is used in an electrical shutter assembly of a camera. A septum electromagnet is conventionally used to introduce particle beams into and extract particle beams from a charged particle accelerator.
