GEOLOGY

Detailed explanation-1: -The magnetic field is the area around a magnet that has magnetic force. 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.

Detailed explanation-2: -Around a permanent magnet or a wire carrying a steady electric current in one direction, the magnetic field is stationary and referred to as a magnetostatic field.

Detailed explanation-3: -Review: The magnetic lines of force, indicate the region in which the force of the magnet can be detected. This region is called the magnetic field. The magnetic lines of force, or flux, leave the north pole and enter the south pole.
