Laterite - Wikipedia

Laterite is both a soil and a rock type rich in iron and aluminum and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock, usually when there are conditions of high temperatures and heavy rainfall with alternate ...

Is Nickel Magnetic? - Techiescientist

Aug 02, 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.
