Electromagnets

Electromagnets are very widely used in electric and electromechanical devices, including:

• Motors and generators
• Transformers
• Relays
• Electric bells and buzzers
• Loudspeakers and headphones
• Actuators
• Magnetic recording and data storage equipment: tape recorders, VCRs, hard disks
• MRI machines

Scientific equipment such as mass spectrometers

• Particle accelerators
• Magnetic locks
• Magnetic separation equipment, used for separating magnetic from nonmagnetic material, for example separating ferrous metal from other material in scrap.
• Industrial lifting magnets
• magnetic levitation, used in maglev trains
• Induction heating for cooking, manufacturing, and hyperthermia therapy
