👉 The term "multipole" refers to a system of charges in quantum mechanics that allows for the quantization of electric and magnetic fields, which are considered as vectors. In other words, it is a mathematical representation of how electric and magnetic fields can be combined or superpositioned. Multipoles are typically described using spherical coordinates (x, y, z), where x, y, and z represent the polar angles of the charges in the system. The magnitude of each multipole vector can be determined
