The magnetic moment of a substance is a measure of the strength of its magnetism. It is the product of the number of unpaired electrons and the Bohr magneton. The magnetic moment is a vector quantity, meaning it has both magnitude and direction. The Gouy balance is an experimental technique used to measure the magnetic moment of a substance. The magnetic moment of a substance does not depend on its temperature, as long as the temperature is below the Curie temperature, above which the substance loses its magnetic properties.
