Question

can we freely suspend a current carrying straight wire ?
If yes, will it also arrange itself in North-south direction like a bar Magnet ?

please answer ​

Answer 1

Explanation:

The wire behaves like a bar magnet.

Answer 2

Explanation:

The earth behaves as a magnetic dipole . Therefore a freely suspended magnet always points towards in the north-south direction because the north pole of the suspended magnet attracts the south pole of the earth's magnet which is the geographical north pole of the earth.

The magnetic field lines of a simple magnet are shown in the picture below. They point from the north pole to the south pole. ... They go right through it, so that inside the magnet the magnetic field points from the south pole to the north pole. Thus the magnetic field lines form a closed loop and do not have any ends.
