The big picture
Here is the whole track on one screen.
| Idea | Remember |
|---|---|
| What a magnet pulls | Iron, nickel, cobalt and steel. Not every metal. |
| Poles | Every magnet has two. The pull is strongest at the ends. |
| Cutting a magnet | Each piece gets its own N and S. |
| Push or pull | Opposite poles pull. Matching poles push. |
| Distance | The pull crosses a gap. It passes through paper, glass, cloth and water. |
| Uses | Fridge door, knife strip, pencil box, compass. |
| Making and losing | Stroking steel makes a magnet. Drops, hits and heat weaken it. |
| The compass | A magnet that swings freely stops in a north-south line. |
| Safety | Keep magnets away from phones, TVs and computers. |
