Across
- 2. A wire formed into a loop carrying current that rotates in a magnetic field because forces act in opposite directions on each side.
- 3. A wire through which electric current is flowing and which experiences a force in a magnetic field.
- 6. The region around a magnet or current where magnetic forces act.
- 10. Charged particles in motion.
- 11. A rule used to determine the direction a current-carrying wire moves in a magnetic field.
- 12. The rotating coil of wire inside a motor through which current flows.
- 13. Electric current in which charges flow in only one direction (such as from a battery).
- 15. The current produced when a conductor moves through a magnetic field or when the magnetic field changes.
Down
- 1. Electric current that constantly reverses direction.
- 4. A device that measures small electric currents using the rotation of a needle attached to an electromagnet.
- 5. A device that increases or decreases voltage using two coils of wire wrapped around an iron core.
- 7. A part of a motor that reverses the direction of current in the armature so it can keep spinning.
- 8. The process of generating an electric current from the motion of a conductor through a magnetic field.
- 9. The force experienced by a moving charged particle in a magnetic field.
- 14. A device that uses electric current to turn an axle and transform electrical energy into mechanical energy.
