A wire is placed at right angles to a uniform magnetic field. There is a current in the wire and it experiences a force. Beams of alpha-particles, beta-particles and neutrons are fired into the magnetic field in the same direction as the conventional current in the wire. Which beams experience a force that is initially in the same direction as the force experienced by the current-carrying wire?
