magnetic properties of nickel

Nickel - Wikipedia

Nickel is a silvery-white metal with a slight golden tinge that takes a high polish. It is one of only four elements that are magnetic at or near room temperature, the others being iron, cobalt and gadolinium. Its Curie temperature is 355 °C (671 °F), meaning that bulk nickel is non-magnetic above this temperature. The unit cell of nickel is a face-centered cube with the lattice parameter of 0.352 nm, giving an atomic radiusof 0.12

Is Nickel Magnetic? - Techiescientist

Aug 12, 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.
