In this deck, we'll explore the fascinating link between magnetism and electricity. You'll learn about the generator effect, which is how we can use motion and magnets to create electricity. We'll see how this principle is applied in generators like alternators and dynamos, and even in microphones. Finally, we'll investigate transformers, essential devices that change voltages and make our national electricity grid possible.

In the 19th century, scientists discovered that electricity could create magnetic fields. This led to a crucial question: could magnetic fields create electricity? The answer is yes. If you move a wire through a magnetic field, or move a magnet near a wire, a potential difference is induced across the ends of the wire. This process is called electromagnetic induction.

This phenomenon, electromagnetic induction, is also known as the generator effect, because it's the principle that all generators use to produce electricity. It's important to remember that inducing a potential difference doesn't automatically mean a current will flow. For a current to flow, the wire must be part of a complete circuit.
