The Air Powered Car Experiment pushes the piston backward by compressed air, and the piston rod drives the rack and gear to rotate, so that the car can move forward rapidly. The principle and application of increasing air density to convert gas pressure energy into kinetic energy are studied through experiments.

When the water is heated and vaporized into water vapor, the volume expands at the same time, generating air pressure to push the piston to move, generating mechanical energy, giving the flywheel an initial speed, pushing the piston to move back and forth, and driving the motor to generate electricity through gears. Understand the basic principle and application of steam engine through experiments.

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.

The basic circuits include oscillator, microphone preamplifier, automatic gain control, filter circuit, speaker drive circuit, etc. It has high quality and natural speech restoration technology.
Read MoreSend InquiryMotor 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.
