state any three Practical uses of Electromagnet in our life
Answers
Answer:
In many practical applications of electromagnets, such as motors, generators, transformers, lifting magnets, and loudspeakers, the iron core is in the form of a loop or magnetic circuit, possibly broken by a few narrow air gaps.
Answer:
A portative electromagnet is one designed to just hold material in place; an example is a lifting magnet. A tractive electromagnet applies a force and moves something.[8]
Electromagnets are very widely used in electric and electromechanical devices, including:
Motors and generators
Transformers
Relays
Electric bells and buzzers
Loudspeakers and headphones
Actuators such as valves
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 a maglev train or trains
Induction heating for cooking, manufacturing, and hyperthermia therapy
