GEOLOGY

Detailed explanation-1: -Solution: (i) False; A magnet of any shape always has two poles: a north pole and south pole.

Detailed explanation-2: -The two ends of a magnet are called poles and are always different from each other. The end that points north, if allowed to move freely, is called the north pole. The other end is the south pole. These magnetic poles behave rather like electric charges.

Detailed explanation-3: -The location of the poles as the magnet can be determined by suspending it freely. A freely suspended bar magnet always points in a north−south direction. The end that points towards north direction is the north pole of the magnet while the end that points towards the south direction is the south pole of the magnet.

Detailed explanation-4: -Every magnet has two sides: a north pole and a south pole. We use these names because if you hang a magnet from a thread, the magnet’s north pole points (almost) towards the north direction.
