What is intrinsic coercivity (Hci)?
If the coercivity of a magnet is the force required to cancel out the magnetic field of a saturated magnet, then intrinsic coercivity is the force required to permanently demagnetize a magnet. Neodymium magnets show large differences between coercivity and intrinsic coercivity, so demagnetizing a neodymium magnet requires much more energy than simply cancelling out (reducing to zero) its magnetic field. Intrinsic coercivity is measured in kilo-oersteds (kOe).
Every neodymium magnet has an associated intrinsic coercive force, which is shown on the 'Neodymium magnet types' page of our Tech Center.
