What Is a Magnetic Field?


A magnetic field is the mathematical expression of the field of influence for magnetic materials and electric currents. A magnetic field is usually expressed in the magnitude and the direction in the same way like a vector field.

A magnetic field is a field which exerts magnetic force on substances that are sensitive to magnetism. A classic example of a magnetic field is the field formed by an iron magnet; to see how the energy in such a field works.
A magnetic field is a field of force produced by moving electric charges. It is also produced by electric fields that vary in time and by elementary particles that possess their own 'intrinsic' magnetic field. It is a relativistic effect which is usually modelled as a spin of the particle.
A magnetic field is the energy force that surrounds the poles of a magnet. The field is created when charges move, in the same way electrical current moves through a length of wire.
