To demagnetize a saturated magnet, a certain magnetic field must be applied, and this threshold depends on coercivity of the respective material. Hard materials have high coercivity, whereas soft materials have low coercivity.aterials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include iron, nickel, cobalt, some alloys of rare earth metals, and some naturally occurring minerals such as lodestone.
Atahualpa was the last Inca ruler, executed by Spanish conquistador Francisco Pizarro in 1533, marking the end of the Inca empire.orn c. 1502, Atahualpa was the younger son of Inca ruler Huayna Capac.
