Electricity & Magnetism
📋 What it is
Electricity is moving charge; it and magnetism are linked — one can create the other.
🗣️ Coach says
Electricity is the flow of tiny charges through a path (a circuit). Amazingly, electricity and magnetism are two sides of one coin: moving electricity makes a magnetic field, and a moving magnet can make electricity. That link runs every motor and generator on Earth.
🧠 Memory hook
Electricity = moving charge. Electricity and magnetism create each other.
😂 Giggle
Why did the photon refuse to check a bag at the airport?
It only travels light!
😲 Whoa!
Every electric motor — from a toy car to a train — works because electricity flowing through a coil turns it into a magnet.
✅ Quick check: What do you need for electricity to flow and light a bulb?
Say your answer out loud first — then reveal.
A complete circuit — an unbroken path (usually with a power source) for the charge to flow around.
Charge only flows through a closed, complete circuit.
🧪 Try it! (2 minutes)
Wrap wire around a nail and touch it to a battery — it becomes a magnet that picks up paperclips (an electromagnet).
