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.

Detailed explanation-2: -Magnetism is produced by electric current. A magnet will always have a pair of poles, a north and south because magnetic field lines are originated from north pole and terminated at south pole and always form closed loops.

Detailed explanation-3: -All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field.

Detailed explanation-4: -What are the two poles of a magnet? The north pole and south pole are the two poles of a magnet.
