Across
- 3. a region around a magnetic material or a moving electric charge within which the force of magnetism acts.
- 7. drive or force (an attack or attacker) back or away
- 9. a north-seeking pole of a magnet
- 13. a field of force that consists of both electric and magnetic components, resulting from the motion of an electric charge and containing a definite amount of electromagnetic energy.
- 14. the south-seeking pole of a magnet
- 15. a substance which does not readily allow the passage of heat or sound.
- 16. a physical phenomenon produced by the motion of electric charge, resulting in attractive and repulsive forces between objects.
- 17. is useful for predicting and visualizing molecular structures.
- 18. an electrical charge on an object that occurs when it has more protons than electrons
- 19. energy that travels in waves, including radio waves, microwaves, visible light, and X-rays
- 20. emit (energy, especially light or heat) in the form of rays or waves
Down
- 1. a form of radiation that is created when an electric field and a magnetic field interact
- 2. region at each end of a magnet where the external magnetic field is strongest
- 4. an atom or molecule with a net electric charge due to the loss or gain of one or more electrons
- 5. a substance or material that allows electricity to flow through it
- 6. An electric current is a flow of charged particles,
- 8. any natural force in the Universe that draws one mass towards another
- 10. Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from Earth's interior out into space
- 11. an electrical charge where an object has more electrons than protons, resulting in a surplus of negative charge carriers, like electrons, and causing it to be attracted to positively charged objects
- 12. a dynamo or similar machine for converting mechanical energy into electricity.
