The InductorIn our tutorials about Electromagnetism we saw that when an electrical current flows through a wire conductor, a magnetic flux is developed around the conductor producing a relationship between the direction of this magnetic flux which is circulating around the conductor and the direction of the current flowing through the same conductor. This well known relationship between current and magnetic flux direction is called, “Fleming’s Right Hand Rule”.But there is also another important property relating to a wound coil that also exists, which is that a secondary voltage is induced into the same coil by the movement of the magnetic flux as it opposes or resists any changes in the electrical current flowing it.
