Charged Particle in a Magnetic Field Suppose that a particle of mass moves in a circular orbit of radius with a constant speed . As is well-known, the acceleration of the particle is of magnitude , and is always directed towards the centre of the orbit.

Negatively charged particles called electrons orbit around the nucleus in different layers, or orbitals. (Unlike this diagram, there is a vast space between the nucleus and the electron orbitals.
