Reluctance is hesitation or unwillingness to do something. When you really don't want to go out in the rain, this is an example of reluctance. reluctance. reluctance. The state of being reluctant; unwillingness. Physics A measure of the opposition to magnetic flux, analogous to electric resistance. reluctance.
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.
