Answer 1

★ Required Answer ★

An electromagnet does not attract a piece of iron.

$\boxed { \large \bf \red { False!!} }$

How?

$\implies$ This is because electromagnets have the property to attract magnetic materials. Since iron is a magnetic material , so an electromagnet can attract a piece of iron.

An electric bell has an electromagnet.

$\boxed { \large \bf \green { True!!} }$

How?

Yes, this statement is true that electromagnets are used in electric bells. When we press the switch of the bell, electric current flows into electromagnets in the bells. And then it attracts the iron strip and the hammer attached to the strip that hits the gong and produces sound.

Do you think an electromagnet can be used for separating plastic bags from a garbage heap?

★ No, I think an electromagnet can't be used for separating plastic bags from a garbage heap.

This is because electromagnet can only seperate magnetic material like iron, cobalt, nickel and many magnetic products from the garbage.

Plastic bags are non-magnetic material, thus it can't be seperated by an electromagnet.

Electromagnet has the property to only attract magnetic material. ★
