Answer 1

Answer:

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.

Answer 2

Answer:

Electromagnet: An electromagnet is a temporary strong magnet made by passing current in a coil wound around a piece of soft iron. It is an artificial magnet.

Explanation:

Characteristics of electromagnet:

1. It is made up of soft iron.
2. The magnetic field strength can be changed.
3. The polarity of an electromagnet can be reversed.
4. It produced temporary magnetic field.
5. It can be easily demagnetized by switching off the current.

Types of electromagnet (shape):

• I-shaped (bar) magnet,
• U-shaped (horse-shoe magnet)
