ElectromagnetsConceptual concept
Check understanding
- Describes that a current-carrying wire produces a circular magnetic field
- Lists three factors that affect electromagnet strength: current size, number of coil turns, and core material
- Explains why an electromagnet can be switched on and off, unlike a permanent magnet
“If your child built an electromagnet using a battery, wire, and iron nail, could they describe two ways to make it pick up more paperclips — and explain why it stops working when the circuit is switched off?”
