Yantra Cathode Cathod Ray Tube with 110V Power Supply Transparent Educational Toys Science Kit Experiment Equipment Magnetic Effect Tube
★ The Cathod Ray tube comes with a 110v POWER SUPPLY ★ 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 (i.e., electron flow). ★ Straight
