SUMMARY
Inductors create a magnetic field that opposes changes in current, known as counter electromotive force (EMF). This opposition is not due to the strength of the magnetic field itself but rather the rate of change of current and the number of turns in the coil. A static magnetic field does not inhibit electron flow in a conductor; only a changing magnetic field can induce an EMF. The effectiveness of an inductor in resisting current changes is determined by its design and the dynamics of the electrical circuit.
