Magnet term "Coercivity"

Sign:
Hc (Hcb or bHc for coercivity, Hcj, Hci, or iHc for intrinsic coercivity)

The strength of external magnetic field to reduce the magnetic flux density or magnetization (polarization) to zero. The later is often called "Intrinsic Coercivity" in order to distinguish from the former.
