Across
- 5. device that uses electromagnetic induction to induce electrical current by rotating loops of wire through a magnetic field
- 6. material that allows electrons to move easily through it
- 7. strong temporary magnet made by inserting an iron core into a wire coil and passing an electric current through the coil
- 9. device that contains a rotating electromagent that changes electrical energy to mechanical energy
- 10. an electric circuit where the current has only one path; if the path is interrupted at any point, it stops current flow in the entire circuit
- 12. a force that affects subatomic particles and other objects that contain electrical charge
- 13. a piece of metal with a strong attraction to another metal object
- 15. material that does not allow electrons to move through it easily
- 16. an electric circuit where the current flows through more than one path; if one path is interrupted, current will still flow through the other parts
- 17. a coiled wire with a charged current running through it
Down
- 1. property of some materials in which there is a force of repulsion or attraction between certain like and unlike poles
- 2. flow of charged particles, such as electrons or ions
- 3. electrical current is induced in a wire when it is moved through a magnetic field
- 4. opposotion to the flow of electrons through a conductor; measured in ohms
- 8. device that can increase or decrease the voltage of an alternating current
- 11. region around a magnet where magnetic forces act
- 14. unalike poles ________
