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.
An electron is a negatively charged subatomic particle. It can be either free (not attached to any atom), or bound to the nucleus of an atom. Electrons in atoms exist in spherical shells of various radii, representing energy levels. The larger the spherical shell, the higher the energy contained in the electron.
