Project Description

Magnetic susceptibility is a measure of how magnetized a material will become in an applied magnetic field and determines whether it will be attracted or repelled by a field. It can be used by geologists to gain insight into the composition of rocks and other geological materials and by chemists to study the structure of molecules. We studied the magnetic susceptibility of fifteen materials using a Gouy balance which works by looking at the change in mass reading when a magnetic field is applied to a sample. In this video we take you through the process of using the Gouy balance while introducing you to some of the physics behind magnetism.
