Question

state various advantages and applications of electromagnet

Answer 1

The main advantage of an electromagnet over a permanent magnet is that the magnetic field can be quickly changed by controlling the amount of electric current in the winding. However, unlike a permanent magnet that needs no power, an electromagnet requires a continuous supply of current to maintain the magnetic field.

Electromagnets are widely used as components of other electrical devices, such as motors, generators, electromechanical solenoids, relays, loudspeakers, hard disks, MRI machines, scientific instruments, and magnetic separation equipment. Electromagnets are also employed in industry for picking up and moving heavy iron objects such as scrap iron and steel.

Answer 2

Explanation:

ADVANTAGES OF ELECTROMAGNET:-

(1). MAGNETIC FIELD CAN BE INCREASED OR DECREASED BY CHANGING THE AMOUNT OF CURRENT.

(2). MAGNETIC POWER IS MORE THAN THAT OF PERMANENT MAGNET

APPLICATIONS:-

IT IS GENERALLY USED IN ELECTRONIC DEVICES SUCH AS GENERATOR,MOTOR,ETC
