Cathode Ray Tube (magnetic Effect Tube) Junior High School Physics Electromagnetism Experimental Experiment Teaching Aids - Educational Equipment

3, pay attention to the wiring according to the wiring diagram, proofread the power supply voltage, check the error can be demonstrated. Straight-in cathode ray tube: Demonstrate the phenomenon that the cathode ray moves in a straight line and can be blocked by metal. Magnetic field effect cathode ray tube: Demonstrates the phenomenon that the ray is deflected in the magnetic field, indicating that the cathode ray is a charged particle stream emitted from the cathode. Mechanical effect polar ray tube: Demonstrates the phenomenon that the cathode ray causes mechanical motion of the object, indicating that the cathode ray has momentum and energy. Electrostatic effect cathode ray tube: Demonstrates the phenomenon that the cathode ray deflects in the electric field, which proves that the cathode ray is a negatively charged particle stream (ie, electron flow).
