Question

How can we find north pole and south pole in bar magnet

Answer 1

Answer:

One easy way to tell which pole is north and which is south is to set your magnet near a compass. The needle on the compass that normally points toward the north pole of the Earth will move toward the magnet's south pole.

Answer 2

Answer:

In a bar magnet the north pole and the south poles are written on the respective sides. Or else take a circular magnet. Bring the north pole close to the end of bar magnet . if it attracts then it is south pole and if it repels it is south pole.
