- 4. the phenomenon where a flowing electric current generates a magnetic field around it
- 9. the flow of electricity in an electronic circuit, and to the amount of electricity flowing through a circuit
- 10. the area around a magnet in which the effect of magnetism is felt
- 12. an imbalance of protons and electrons, where there are more protons than electrons
- 14. to force away or back, or to resist or fight against
- 17. a physical property of matter that causes it to experience a force when placed in an electromagnetic field.
- 18. phenomenon associated with magnetic fields, which arise from the motion of electric charges
- 19. If you align two magnets so the south pole of one faces the north pole of the other, the magnets will move towards each other. The opposite forces _______ each other
Down
- 1. it carries a negative electrical charge
- 2. the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light.
