Electricity/Magnetism

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.

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.)
