Question

Why does a magnetic compass needle pointing North and South in the absence of a nearby magnet gets deflected when a bar magnet or a current carrying loop is brought near it. Describe some salient features of magnetic field lines concept.

Answer 1

Explanation:

because in compass needle is made up of metal that's why Needle deflected when bar magnet or a current carrying loop is brought near it

features of magnetic field lines are as follows :-

# magnetic field lines are imaginary lines used to show magnetic field

# these are closed continuous curves

# when magnetic field lines closer in the region where Magnetic field strong

# Magnetic field lines do not intersect each other

# the direction of magnetic field lines is from south pole to north pole

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.
