Magnetic properties of marine limestones

Numerous paleomagnetic investigations have been carried out on limestones, but their rock magnetic properties have often been neglected. In this review, geological and rock magnetic factors which determine whether marine limestones are suitable for paleomagnetic study are summarized, and laboratory techniques for the identification of the magnetic mineralogy are evaluated.

Magnetic Properties: Mineral Properties

Magnetic properties of minerals are defined as follows: Ferromagnetism describes strong attraction to magnetic fields. This property is exhibited in few minerals, notably Magnetite and Pyrrhotite . Paramagnetism is weak attraction to magnetic fields. The attraction is usually discernible, but it may be so weak that it is undetectable.

Is Nickel Magnetic?

 · 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.
