About This

• ◆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.
• ◆Straight-in cathode ray tube: Demonstrate the phenomenon that the cathode ray moves in a straight line and can be blocked by metal.
• ◆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).
• ◆Scope of application: Teachers teach in laboratory classrooms to increase students' interest in physics and electricity.This product is a glass product and it is inevitable to cause damage during transportation.
