Magnetism & Electromagnetism
📋 What it is
Magnets have poles; moving electricity makes magnetism, which runs motors and generators.
🗣️ Coach says
Every magnet has two poles — like poles push apart, opposites pull together. The big idea: moving electricity creates magnetism, and a moving magnet creates electricity. That two-way link powers every electric motor and every generator that makes your electricity.
🧠 Memory hook
Opposite poles attract; moving electricity ⇄ magnetism runs motors and generators.
😂 Giggle
Why was the science show so electrifying?
Because the static electricity trick really sparked interest!
😲 Whoa!
The electricity in your home is made by spinning magnets past coils of wire — huge versions of the same effect you can make with a battery and a nail.
✅ Quick check: What happens if you bring two NORTH poles of magnets together?
Say your answer out loud first — then reveal.
They push apart (repel) — like poles repel, opposite poles attract.
Magnetic poles repel like-to-like and attract opposite pairs.
🧪 Try it! (2 minutes)
Bring two magnets together both ways. One way they snap together, flip one and they push apart.
