1698 - How do generators and transformers work on the principle of electromagnetic induction?

Imagine you have a magnet and a coil of wire. When you move the magnet near the coil, electricity starts flowing in the coil. This is called electromagnetic induction.

Generators: A generator is like a machine that uses movement to create electricity. It has a magnet and a coil of wire. When the magnet spins near the coil, it induces electricity in the coil. The movement of the magnet creates a flow of electrons, which becomes the electricity we use.

Transformers: A transformer is like a machine that helps change the size of the electricity. It has two coils of wire, one wrapped inside the other. When electricity flows through the first coil, it creates a magnetic field that induces electricity in the second coil. By changing the number of turns in the coils, the transformer can increase or decrease the voltage (size) of the electricity.

In simple words, both generators and transformers use magnets and coils to convert movement or energy into electricity, or to change the size of electricity.
