Across
- 3. type of magnet in which the magnetic field is produced by an electric current.
- 5. the force given off by an object that pulls other objects towards
- 7. area surrounding charged particles that can be exerted on other charged particles
- 9. Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.
- 11. an object or type of material that allows the flow of charge in one or more directions.
- 12. An electrical insulator is a material in which electric current does not flow freely.
Down
- 1. a physical phenomenon produced by the motion of electric charge, resulting in attractive and repulsive forces between objects.
- 2. a measure of the opposition to current flow in an electrical circuit.
- 4. external force given off by a magnet, strongest at the poles
- 6. stream of charged particles, such as electrons or ions, moving through an electrical conductor or space.
- 8. the production of an electromotive force across an electrical conductor in a changing magnetic field.
- 10. A characteristic that is either positive or negative
