Across
- 2. a wire made into a coil is a solenoid
- 5. inside a solenoid the magnetic field is strong and uniform
- 6. electromagnets can be used to lift cars
- 7. increasing the number of coils on a solenoid strengthens the electromagnet
- 8. decreasing the current weakens the electromagnet
- 9. and sort out scrap metals
Down
