GEOLOGY

Detailed explanation-1: -Magnets have two poles, a north pole and a south pole. The magnetic field is represented by field lines that start at a magnet’s north pole and end at the south pole. When most people think of magnetism, they think about the magnetic force experienced between two magnets.

Detailed explanation-2: -Answer: Solution: (i) False; A magnet of any shape always has two poles: a north pole and south pole.

Detailed explanation-3: -Experimentation shows that all magnets have two poles. If freely suspended, one pole will point toward the north. The two poles are thus named the north magnetic pole and the south magnetic pole (or more properly, north-seeking and south-seeking poles, for the attractions in those directions).

Detailed explanation-4: -Well bar magnets have two poles, so their magnetic fields are called dipole which means–you guessed it–two poles!
