02-08-2021· Nickel (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.
Is Nickel Magnetic? The element Nickel (Ni) is one of the few ferromagnetic metals. Ferromagnetic means they are attracted to magnets and can be magnetized themselves. Most metals aren't magnetic with the exception of iron, nickel, cobalt, gadolinium, neodymium and samarium.
