Magnetic, Electrical, Gravitational forces terminology
Across
- 3. a combination of invisible electric and magnetic fields of force
- 7. a process in which a conductor is put in a particular position and magnetic field keeps varying or magnetic field is stationary and a conductor is moving
- 9. a substance which does not allow the passage of heat or sound
- 10. the south pole of a magnet
- 11. a property of an object that has more protons than electrons
- 14. A material that is both electrically conductive and magnetic
- 15. when you put two alike poles together, (North pole to North pole or South pole to South pole) they will repel each other
- 18. The magnetic field that protects Earth from cosmic radiation and from the charged particles emitted by our sun
- 20. one of the instruments for measuring electrical current par excellence
- 22. the area around a magnet in which the effect of magnetism is felt
Down
- 1. The force that pulls 2 magnets together when their opposite poles are facing each other
- 2. a form of radiation that travel through the universe
- 4. when an object has more electrons than protons, resulting in an excess of negative charge
- 5. radiant energy that travels in waves at the speed of light
- 6. the north pole of a magnet
- 8. theory The valence shell electron pair repulsion theory is a model used to predict 3D molecular geometry based on the number of valence shell electron bond pairs among the atoms in a molecule or ion
- 12. points of Earth’s surface where the magnetic field is vertical, and the ends of a magnet where the magnetic field is strongest
- 13. If electrons are accelerated up and down the wires in the antenna, changing electric and magnetic fields will be produced in a similar manner to the electrons changing energy levels in atoms
- 16. generators use magnetism to produce electricity by moving a conductor through a magnetic field
- 17. phenomenon associated with magnetic fields, which arise from the motion of electric charges
- 19. an atom or molecule with a net electric charge due to the loss or gain of one or more electrons
- 21. The flow of electricity in an electronic circuit, and to the amount of electricity flowing through a circuit
