Electric Bell Experiment

Electric Bell Experiment uses the magnetism produced when the electromagnetic current passes through to draw the shrapnel under the small hammer to strike the bell. At the same time, the circuit is disconnected, the electromagnet loses its magnetism, the small hammer is bounced back again, the circuit is closed and repeated, and then a continuous hitting sound is produced. Understand the working principle and application of electromagnet through experiment.

Motor Experiment

Motor Experiment uses the electromagnetic induction principle that the electrified coil moves in the magnetic field to make the motor model. The electrified coil is the enameled wire wound on the silicon optical sheet, which has three groups in total. The electrified coil rotates under the force in the magnetic field. Through experiments, we know that electric energy can be converted into kinetic energy.

Funny Game Of Electric Conduction

Funny game of electric conduction is composed of modeling conductive metal, LED lamp and buzzer. When the metal hook of the electric shock rod contacts with the conductive metal wire, the whole circuit forms a path, the buzzer will ring, the LED lamp will be on, if not, the circuit will be open, and the whole circuit will not work. The hand eye coordination ability of children was developed through experiments.
