Magnetizing force needed to reduce residual magnetism in a material to zero. also see: AKA: Antonym: Source: http://www.twysted-pair.com/dictionary.htm

Magnetic field created by current flow alone. The unit of measure is the Oerstad.

The demagnetizing force, measured in Oersteds, necessary to reduce observed induction, B, to zero after the magnet has previously been brought to saturation.

That value of magnetizing force required to reduce the flux density to zero.

A negative or reverse magnetic force applied for reducing magnetic induction to zero.

(H) Magnetizing force needed to reduce residual magnetism in a material to zero.

The amount of applied magnetic field that is required to overcome the magnetic induction of a ferromagnetic material and bring its residual magnetism back to zero; i.e., the force required to demagnetize a material.

Hc (Oersted): The magnetizing field strength required to bring the magnetic flux density of a magnetized material to zero
