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.
Electric charge is a basic property of elementary particles of matter. The protons in an atom have a positive charge, while its electrons have a negative charge. In an ordinary atom, the number of protons equals the number of electrons, so the atom is electrically neutral. If an atom gains some electrons, it becomes negatively charged.
