Electricity and Magnetism
Across
- 3. a north-seeking pole of a magnet
- 6. closed circuit where the current follows one path
- 10. a flow of electric charge carried by moving electrons
- 12. material that doesn't conduct electricity
- 16. ends of a magnet where the force is the strongest
- 17. turns the circuit on of off/ closes and opens circuits
- 19. there are two on a magnet, north and south
