noun (Electrical engineering: Circuits, Electrical power, Computing and control) The reluctance of a magnetic material is its ability to oppose the flow of magnetic flux. ⇒ The magnetic flux created by the field windings follows the path of least magnetic reluctance. ⇒ An excessive current may be due to a partial short circuit between one or more turns in the winding or it may be due to some defects in the magnetic circuit which alter the reluctance of the core. ⇒ The reluctance of a magnetic material is its ability to oppose the flow of magnetic flux.
