A bar magnet has no markings to indicate its poles How would you find out' near which end is its North pole located?

Answer:

We can find out a direction by freely suspending a bar magnet. We will find that freely suspended bar magnet always comes to reset in a North- South direction. The end of the magnet that points towards North is called North pole. The other end that points towards South is called South pole.
