A Crookes tube is an early experimental electrical discharge tube, with partial vacuum, invented by English physicist William Crookes in which cathode rays, streams of electrons, were discovered.
Crookes put a magnet across the neck of the tube, so that the North pole was on one side of the beam and the South pole was on the other, and the beam travelled through the magnetic field between them. The beam was bent down, perpendicular to the magnetic field.
