Answer 1

Answer:

The magnetic induction lines come out of the North Pole and enter the South Pole, forming a closed curve from the South Pole to the North Pole inside the magnet. The two magnetic induction lines never intersect. The earth itself is a huge magnet. Because the geographic poles do not coincide with the geomagnetic poles, the north-south direction indicated by the magnetic needle is not the north-south direction of geography, but slightly deviated. Every magnet has the North Pole and the South Pole, and its two poles always exist in pairs. When we make strong magnets for customers, these permanent polar magnets have no pole mark if there is no special requirement. But if you want to ask how to determine north and south pole of magnet

Answer 2

Explanation:

In the magnetic field line we can clearly see that at point P the field lines are moving out of the bar and at Q the field lines are moving in. ... when in a bar field line moves out the it is South Pole. hence, Point P is North Pole. Point Q is South Pole.
