When the aluminum plate connected with the pointer will produce some eddy current, there will also be magnetic effect. Along with the magnetic field, the magnetism of the magnet and the eddy current on the aluminum disk will also attract and repel each other

Through experiments, we can understand the structure and principle of radio.
Read MoreSend InquiryElectric Shooting Experiment consists of a photoelectric control circuit composed of a photoelectric receiving tube and a laser light-emitting tube. When the photoelectric receiving tube receives a strong infrared laser, it is sent to the main control circuit U1 for processing, and then output to the horn to read out the voice of the laser gun hitting the receiving tube. Understand the principle and application of optical switch through experiment.
