What is magnetic susceptibility? Explain how it relates to magnetisation and provide two applications that commonly use magnetic susceptibility.

Answer: Magnetic susceptibility is way to measure how attracted or repelled a material is when exposed to a magnetic field.

Explanation: Magnetic susceptibility is related intimately to magnetization, since this is the procedure of exposing some material to a magnetic field itself, turning it permanently or momentarily magnetic. A magnetic field has permanent dipole moments between two magnetic materials, creating electric currents. Two examples of its applications are for paleomagnetic studies in geology and also structural geology.
