WebIt is called induction because the current is said to be induced in the conductor by the magnetic field. Induction is measured in unit of Henries (H). Inductance When induction occurs in an electrical circuit and affects the flow of electricity it is called inductance (L). WebAn induction hob has a coil, powered by an alternating electric current, underneath a ceramic plate. The alternating current produces an oscillating magnetic field, which induces an oscillating magnetic flux in the base of a pan placed on the hob. This produces an electric current (called an eddy current) in the pan base, heating it up. boric takes office
