Electromagnetic forces and relative motion


Consider the case where a charged particle is moving in a magnetic field in a lab. In the rest frame of the lab, the charged particle moving through the field feels a Lorentz force which deflects the particle. In the frame of the particle, it is at rest and therefore does not feel a Lorentz force. Observers in both frames must agree regarding the deflection of the particle.
