Question

Why do we see the deflection in magnetic compass when brought near a current carrying condu?

Answer 1

$\underline{\bold{Answer:-}}$

We see the detection in the Magnetic compass when it is brought near the current carrying conductor because it creates the magnetic field around it.

The direction of these Magnetic field can be see with the help of right hand thumb rule.

In this rule, thumb is kept in the direction of flowing current and then the fingers are folded. The direction in which fingers are folded shows the direction of magnetic field lines formed around the current carrying conductor.

When the current flowing in the conductor Stop then the deflection will also not take place because the magnetic field will not be created around it.

Answer 2

$\bigstar\rm\purple{Answer}\bigstar$

The $\sf{\bold{compass\:needle}}$ is a small magnet. When the compass needle is brought close to a bar magnet, the magnetic field lines of the compass needle interact with the magnetic field lines of bar magnet, which causes the compass needle to deflect.
