  • * Overview: The electromagnetic damping demonstrator is suitable for the mathematics of the electromagnetic induction part of high school physics. Use the pendulum in the demonstrator to reciprocate between the two magnetic poles of the magnet to observe the electromagnetic damping effect.
  • * Experimental purpose: Observe the phenomenon of the pendulum swinging back and forth between the two magnetic poles of the magnet, and analyze the cause of this phenomenon.
  • * Experimental equipment: metal pendulum, magnet.
  • * Experimental principle: A single pendulum made of a metal plate. When the pendulum reciprocates between the two magnetic poles of the magnet during the swing process, the magnetic flux changes in a certain local area of the pendulum, thus generating an induced electromotive force. In turn, an induction power source is generated, which is the eddy current.
  • * According to Lenz's law, the action of the magnetic field of the eddy current and the original magnetic field hinders the movement of the pendulum. Therefore, the metal pendulum is always subjected to a damping force, just like swinging in a certain viscous medium, and stops quickly In the future, this damping originated from electromagnetic induction, so it is called electromagnetic damping.


[Product Name]: Electromagnetic Damping Demonstrator
[Applicable]: applicable to the mathematics of the electromagnetic induction part of high school physics
[Product weight]: 350g
Instructions:
1. When there is no magnetic field, let the damping pendulum swing freely. It can be observed that the damping pendulum stops after a long time.
2. When the damping pendulum swings back and forth between the two magnetic poles, the damping pendulum will stop quickly, indicating that there is a strong magnetic damping between the two poles.
3. Replace the damped pendulum with a comb-like non-damped pendulum with a gap in the above experiment. Whether it is on the two magnetic poles or not, the swing will take a long time to stop.
Precautions:
The demonstration stand should be placed horizontally on the desktop. Handle all kinds of experimental equipment with care.
