👉 The term "quadrupole" is a term used in the field of nuclear physics and quantum mechanics. It refers to a type of particle that can be created by an electric dipole moment, which is a vector quantity with two opposite signs. The presence of a quadrupole creates a magnetic field that is perpendicular to the electric dipole. This magnetic field is responsible for the electromagnetic force between charged particles in a system. In quantum mechanics, a quadrupole can represent a state where
