Is Nickel Magnetic? - Techiescientist
3 days agoNickel (Ni) is ferromagnetic in nature, because of the parallel alignment of its 2 unpaired electrons or 'spins' in presence of an external magnetic field. Nickel holds its magnetic property even in absence of any magnetic field, which gives permanent magnetization to it. Nickel exists as a silvery-white lustrous metal with a tinge of gold.
