magnetic effect of electric current 2 example answer please​

Answer 1

Explanation:

$\huge \mathbb{ \red {★a} \pink{n}\purple{S} \blue {w} \orange{e} \green{r★}}$

When electric current passes through a wire, the current-carrying wire behaves like a magnet. This is called the magnetic effect of current. The magnetic effect of current is utilised in making electromagnets, electric bells, telephone instruments, electric fans, electric motors, loudspeakers and toys etc.

Answer 2

A solenoid is a cylindrical coil of wire that behaves like a bar magnet when current flows through it. If we insert a piece of iron in a coil carrying current, then iron gets strongly magnetised. This principle is used to make strong electromagnets.
