•  Investigate the deflection of an electron beam by a magnetic field. •  Investigate the deflection of an electron beam by an electric field. •  Construct a velocity filter using orthogonal electric ... more

Electrons in a fine-beam tube are deflected into a circular path by a uniform magnetic field. The tube contains neon gas at a precisely defined pressure so that gas atoms become ionised by collision with electrons along the path thus ... more
