4. A device that changes mechanical energy into usable electrical energy.
6. Electric Field An electric field that has the same magnitude and direction throughout the system.
7. A device that transfers electrical energy from one circuit to another through electromagnetic induction.
9. A temporary magnet where the magnetic field is produced by electric current.
11. May be positive, negative, or neutral can be present on subatomic particles, atom, causes the object to interact with electromagnetic fields or other charged particles.
12. Electricity The accumulation of electric charge on the surface of an object.
13. Field The area around a magnet or moving electric charge that can exert a magnetic force.
14. Law A law describing the electrostatic force of interaction between charged particles based on the strength of the charges and the distance between the particles.

1. Induction The production of electric potential difference across a conductor as the conductor moves through a magnetic field.
2. Charge An ideal particle whose physical properties are negligible.
3. A device that uses different energy sources to produce force and motion.
5. Magnet A material that retains it magnetism after it is removed from a magnetic field and without an electric current flowing through it.
8. A physical condition existing in space that causes particles placed within the space to experience a force.
10. Force The interaction between a charged particle and an electromagnetic field or between two charged particles.
