This exhibit explains the principle of eletro magnetism. It illustrates how electricity is created, how it flows and influences its surroundings.
By moving a magnet fast through a coil, induction voltage is created. The electrical current in a coil generates a magnetic field around the coil.
- Move the handle, and see how the magnet moves through the coil.
- Observe how the movement of the magnet generates an electrical current and magnetic field- indicated by the lamp and the compass.
- Discover how the electrical cur-rent travels through the circuit and makes the bulb glow.
