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. At Huayna's death, the kingdom was divided between his sons. This lead to a bloody civil war, which Atahualpa won in 1532.
The role of Atahualpa was played by Robert Stephens and by David Carradine (who received a Tony Award nomination) in the 1965 Broadway production. Christopher Plummer was Atahualpa in the 1969 movie version of the play.e was given the name Francisco Atahualpa in honor of Francisco Pizarro. In accordance with his request, he was strangled with a garrote on 26 July 1533. Following his execution, his clothes and some of his skin were burned, and his remains were given a Christian burial.
