A magnetic field is the magnetic effect of electric currents and magnetic materials. The magnetic field at any given point is specified by both a direction and a magnitude (or strength); as such it is represented by a vector field. The term is used for two distinct but closely related fields denoted by the symbols B and H, where H is measured in units of amperes per meter (A/m) in the SI. B is measured in teslas (T) and newtons per meter per ampere (N/(m·A)) in the SI. This Magnetic Field Strength converter allows you to convert ampere/meter (A/m), ampere-turn/meter (At/m), Gilbert/meter (Gi/m), kiloampere/meter (kA/m), oersted (Oe), among other units related to Magnetic Field Strength.
