“an electric current flowing in one direction only”.
“current in a coil that gives rise to a m.m.f.( MagnetoMotive Force) in a magnetic circuit, especially in a generator or motor.”
"having both electrical and magnetic properties / of or relating to the interrelation of electric currents or fields and magnetic fields”.
“ region around a magnetic material or a moving electric charge within which the force of magnetism acts.”
“a device that changes power into movement, used to make machines work”; a device that changes electric power into movement.
the production of an electric or magnetic state by the proximity ( with-out contact) of an electrified or magnetized body”/ “ the production of an electric current in a conductor by varying the magnetic field applied to the conductor”.
“machine for producing electric energy / dynamo or similar machine for converting mechanical energy into electricity”.
“an electric current that reverses its direction many times a second at regular intervals, typically used in power supplies”.
