J. J. Thomson discovered the electron using an experiment involving cathode rays and a magnetic field. When subjected to the magnetic field, the cathode ray was deflected. If the magnetic field was flipped, the cathode ray was deflected in the opposite direction. This proved that a cathode ray was a stream of negatively charged particles that would later be deemed electrons.
