Deflection angles of 50 degrees are reportedly possible without measurable deflection aberration. To explain how alpha and beta particles are deflected, the following two figures have been provided in my textbook but without any explanation for the intensity of the deflections shown: I have two theories regarding why the alpha particle was deflected more than the beta particle: The alpha particle has a greater overall charge and hence feels a greater pull towards the (-) plate, The beta particle is travelling much too fast for it to be "properly" deflected & attracted to the positive plate. The secondary electron emission is what causes the beam to form. In magnetic fields charged particles tend to move in circles. At GCSE you do not need to know which way it will move but at A level you do. When a charged particle cuts through a magnetic field it experiences a force referred to as the motor effect. The direction of deflection which can be determined by Flemings left hand rule demonstrates that they must be positively charged. If this angle were \(90^o\) only circular motion would occur and there would be no movement of the circles perpendicular to the motion.
