Electricity/Magnetism
Across
- 3. A field that exerts a force on magnets or on certain metals like iron, nickel, and cobalt.
- 4. The measure of how much pressure the circuit has. (Think of water coming from a garden hose.)
- 6. The measure of how much resistance there is to the flow of electricity. (Only one door opens so you have to funnel out there and it slows/backs things up.)
- 7. Negatively charged particles that can be transferred from one object to another.
- 10. Scientist that discovered the relationship between electricity and magnetism.
- 12. An object or material that generates a magnetic field.
- 13. A field formed when objects collect electric charges.
- 14. A wire coil, sometimes wrapped around a metal core, that produces a magnetic field when electricity runs through the wire.
- 15. The imbalance of positive and negative particles in an object.
Down
- 1. The chemical slurry of ions found in a battery.
- 2. Measures the amount of electrons that are flowing through a circuit. (Think about a crowd of students moving through the hallway)
- 5. A push or pull between two objects.
- 8. The positive or negative ends of a battery
- 9. An instrument that contains a magnetized needle that points toward magnetic north.
- 10. A region around an object that can attract or repel other objects in its area.
- 11. The measure of how powerful the electricity is. (The amount of work that can be done.)
