Magnetic Field is the region around a magnetic material or a moving electric charge within which the force of magnetism acts. A pictorial representation of the magnetic field which describes how a magnetic force is distributed within and around a magnetic material.
A magnetic field is a region around a magnet, or a current carrying conductor, where a magnetic force exist or is experienced. The lines of force of a magnet are used to determine the magnetic field.
A magnetic field is an invisible force field created by an electric current or a permanent magnet. It is a vector field that surrounds a magnetized object and exerts a force on other magnetic materials and electric currents in its vicinity.
