Magnetic dipole

Quality 0.00 · 3 views · Updated 1 month ago

In electromagnetism, a magnetic dipole is a theoretical description of a sufficiently small magnet such as that of an atom or electron. All magnets can be described as being a magnetic dipole for sufficiently large distances from the magnet. The strength of a magnetic dipole is determined by a single property its magnetic dipole moment. The magnetic dipole model accurately predicts many properties of small magnets such as the magnetic field it produces, how it interacts with other magnetic dipoles, and how an external magnetic field will apply a torque or create a net force on the dipole.
