Formula and explanation

Formula: r = (mv)/(|q|B) Conditions: Charged particle's initial velocity is perpendicular to a uniform magnetic field. Explanation: The particle undergoes uniform circular motion in a plane perpendicular to the field. r is the orbital radius, m is the particle mass, v is the speed, q is the charge, and B is the magnetic flux density.
