Cathode ray Tube electrostatic Deflection Tube with Induction Coil Physics Electromagnetic Experiment Equipment

Demonstrate the deflection of the cathode ray tube in the electric field, and prove that the cathode ray is a stream of negatively charged particles. (Ie electron flow) The product consists of blister, baffle, fluorescent plate, electric field electrode, cathode, anode, bakelite seat, etc. Shows that when the electrostatic effect cathode ray tube is demonstrated, first turn on the low-voltage power supply and turn the switch of the induction coil to generate cathode rays, and a band-shaped track appears on the phosphor plate. Then turn on the DC high-voltage current to form an electric field. At this time, when the cathode rays pass through the fluorescent plate, the band-shaped track will be deflected toward the electrode plate with high potential. With the change of the output voltage of the voltage regulating transformer (that is, the change of the DC high voltage causes the change of the electric field intensity), the deflection angle of the band track also changes: according to the deflection of the cathode ray in the electric field, it can be affirmed that the cathode ray is a helper charge The flow of particles, such negatively charged particles are electrons., Manufacturer: ASumPio
