What is an intrinsic coercivity (Hci)?
If the coercivity of a magnet is the force required to balance the magnetic field of a saturated magnet, the intrinsic coercivity is the force required to permanently demagnetize a magnet. Neodymium magnets have large differences between the coercivity and the intrinsic coercivity, so it takes much more energy to balance (reduce to zero) the magnetic field of a neodymium magnet than it does to just balance the magnetic field of a neodymium magnet. The intrinsic coercivity is measured in kilo-oersteds (kOe).
Each neodymium magnet has an associated intrinsic coercive force, which is displayed on the 'Neodymium Magnet Types' page of our Tech Center.
