Definitions: Coercivity: For ferromagnetic material the coercivity is the intensity of the applied magnetic field required to reduce the magnetization of that material to zero after the magnetization of the sample has been driven to saturation. Thus coercivity measures the resistance of a ferromagnetic material to becoming demagnetized.

Reluctivity: It is equal to the ratio of intensity of the magnetic field to the magnetic induction of the material.
