Answer 1

Answer:

Explanation:

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. ...

● Two uses:-

1) electric bells

2) loud speaker

● Factors on which the strength of an electromagnet depends: (i) Number of turns in the coil: The larger the number of turns in the coil, greater is the strength of the electromagnet. (ii) Strength of the current: The larger the current passed through the solenoid, more powerful is the electromagnet.

Answer 2

What is an electromagnet?

A soft metal core made into a magnet by the passage of electric current through a coil surrounding it.

Give two uses of electromagnets.

Headphones and loudspeakers.

Name two factors on which the strength of an electromagnet depends.

• The strength of the current passing through the coil, the greater the current, the greater the strength.

• Whether the core is made up of a soft or hard magnetic material.
