==Abstract==

This paper summarizes experiments that use a vacuum tube to determine the magnetic field necessary to prevent electrons from reaching the anode in a high vacuum diode. In addition to determining this magnetic cutoff for a given electron energy, the experiment includes the determination of the magnetic flux of an air-core solenoid and the calculation of the velocity of 10-volt electrons. This summary also lays the foundation for determining the electron charge-to-mass ratio (e/m) using data collected in this experiment. This experiment is based on the Hull method devised by the inventor of the magnetron diode tube in 1921.[[Category:Scientific Paper]]
