GEOLOGY

Detailed explanation-1: -Magnetic field is the region around a magnet where the magnetic force is exerted.

Detailed explanation-2: -This region is called the magnetic field. If an iron object is near a magnet, but is not within the magnetic field, the object will not be attracted to the magnet. When the object enters the magnetic field, the force of the magnet acts, and the object is attracted.

Detailed explanation-3: -Magnetic Field is the region around a magnetic material or a moving electric charge within which the force of magnetism acts. A magnetic field is a vector field in the neighbourhood of a magnet, electric current, or changing electric field in which magnetic forces are observable.

Detailed explanation-4: -All magnets have north and south magnetic poles. The poles are regions where the magnet is strongest. The force that a magnet exerts is called magnetic force.
