What Are Some Uses of an Electromagnet?
Electromagnets are man-made magnets that are created through the use of electricity. This type of magnet is used in many modern applications and devices.Electric PowerElectricity is produced through the use of generator. A generator uses an outside force (such as wind, water or steam) to rotate a shaft that turns electromagnets. Electromagnetic fields are produced, and they produce electricity.Magnetic TrainsMagLev Trains, or magnetic levitation trains, use electromagnets to allow a train to move across a specially designed track without friction. MagLev Trains can go as fast as 300 mph, and they use electromagnets to lift the train off the track and to propel it forward.Hard DrivesComputers use electromagnets as a part of the hard drive system. Electromagnets are used to write information onto disks. Without electromagnets, it would be impossible to store information on a computer.Electromagnetic TherapyElectromagnets are used in electric therapy to treat disease. Practitioners assert
