VERIMP Demonstrator Damping Demonstrator Experimenter Hollow Aluminum Trong Magnetic Block Plastic Block Electromagnetic Damping Demonstrator Experimental Electromagnetic Instrument Physics

Product Name: Electromagnetic Damping DemonstratorProduct size: 61*3cmFeatures:Aluminum tube: thickened tube body, reasonable designMaterial: carefully selected materials, teaching materials standards, smooth tube body, no unevennessExperiment: simple operation, good experiment effectPrecautions:1 It is best to do the experiment on the desktop. Avoid damage or injury due to the large drop when the object falls2 The instrument should be put back in the box after use to prevent the loss of small objects.

• * Phenomenon: By putting the strong magnetic block and the plastic block into the aluminum tube separately, it can be observed that the permanent magnet cylinder falls slowly and the plastic cylinder falls fast.
• * Principle: Because the strong magnetic block undergoes electromagnetic induction when relative movement occurs through the closed conductor (aluminum tube), electromagnetic resistance is generated, which hinders the movement of the magnetic block, so the permanent magnet cylinder falls slowly.
• * Experiment 1: Put the side of the aluminum tube with the observation window toward the audience and keep it vertical, and insert the permanent magnet cylinder from the upper port of the aluminum tube. The observer can feel through the observation window: the permanent magnet cylinder will be in the aluminum The inner cavity of the tube falls slowly and falls out from the bottom of the aluminum tube. Once the aluminum tube escapes, it falls quickly.
• * Experiment 2: Take out another plastic cylinder with the same size as the permanent magnet cylinder. Re-doing the above experiment will find that the plastic cylinder will fall quickly without any obstacles. If you compare the weight of the cylinder, the plastic cylinder is still significantly lighter than the permanent magnet cylinder.
