Product Principle:

By rotating a disc with magnets, electromagnetic induction occurs between the magnets and the coil, causing a small light to glow. This utilizes the principles of energy conservation and conversion, where the rotation of the strong magnets induces current in the coil, causing the light-emitting diode to glow, thereby achieving the mutual conversion of mechanical energy and electrical energy.

Gameplay Points:

Rotate the disc at slow, moderate, and fast speeds respectively, and observe how the light-emitting diode’s glow changes. When rotating clockwise and counterclockwise, observe how the glow of the light-emitting diode changes in each direction.
