Across
- 4. materials that tend to allow charges to move through them easily
- 6. any piece of material that produces a measurable magnetic field in the space around it
- 7. caused by differences in electric charges
- 11. movement of charge from one terminal to another; measured in amperes (A)
- 12. materials with high electrical resistance
Down
- 1. caused by metals present in the Earth's core; as the Earth rotates, their motion creates a field around the planet from magnetic North to magnetic South
- 2. amount of energy transformed from electric currents by component
- 3. a measure of the difference in energy across a current or component
- 5. materials that are good at "holding onto" electric charges
- 8. want to cancel out their electric charges; only matter that carries an electric charge is affected by electric fields
- 9. harnessed energy that is transformed from electrical to chemical energy; also called a cell
- 10. groups of atoms that exert a force in a same direction
