Inductive Reactance
Inductive Reactance : Electrical current produces heat and/or a magnetic field (such as in the windings of a motor). We refer to the tendency for current flow and changes in flow to be influenced by magnetic fields as inductance. An AC circuit that contains only inductance, capacitance or a combination of the two is defined by the total opposition to current flow expressed in reactance. Inductance only affects current flow when the current is changing. Inductance produces a self-induced voltage (called a counter emf) that opposes changes in current. Obviously, the current changes constantly in an AC circuit. Inductance in an AC circuit, therefore, causes a continual opposition. This opposition to current flow is called inductive reactance
