Faraday's Laws of Induction help us understand how magnets can create electricity. There are two main ideas behind these laws:
First Law: When a magnetic field changes near a conductor, like a wire, it makes an electric current flow in that wire. For instance, if you bring a magnet closer to a coil of wire, you can generate electricity.
Second Law: The size of the electric current created depends on how fast the magnetic field changes. This means that if you move the magnet faster or if you have more loops of wire, you'll create a stronger current.
These ideas are used in generators. In generators, turbines spin magnets around coils to produce electricity.
Think about riding a bike with a dynamo. As the bike wheel turns, it generates power to light up your front lamp!
