Unformatted text preview: A basic principle of relativity is that the physics is the same regardless of which inertial reference frame you are in. Hence, the particle cannot not be undeflected. (Yogi Berra or Casey Stengel?). In other words, the particle must still have zero net force on it and zero acceleration; it is still undeflected. What is the inescapable conclusion forced upon you about the fields in your reference frame that is moving with respect to the magnetic field (how does the magnetic field transform into your reference frame)? You can ask the same question of a charged particle moving with velocity v in a uniform B fieldin the rest frame of the particle there is no magnetic force but in the rest frame of the magnet there is a magnetic force ** Under the complete time reversal operation the B field vector also flips direction because B fields are generated by currents and time reversal changes the directions of these currents. v +...
