Science

6. current- The sum of the currents through each path is equal to the total current that flows from the source
10. force- the attraction or repulsion between magnetic poles
11. opposition to the flow of charges in a material
13. a push or pull of an object
15. ME moves a wire thru a magnetic field, producing current in the wire
17. current- flow of electric charge in only one direction
18. resistor- Two -terminal electrical component that implements electrical resistance as a circuit element
20. device that uses an electromagnet to measure small currents
22. is any material that attarcts iron or other materials that contains iron
23. as a commutator moves, it slides past two contact points
24. current- flow of electrical charge that regularly reverses

1. is used to increase or decrease voltage
2. energy- energy an object has due to its motion
3. induction- is the production of an electromotive force across an electrical conductor in a changing magnetic field.
4. to the opposite sides (north and south)
5. motor- a device that uses an electric current to turn an axle
7. is the force of attraction or repulsion of a magnetic material due to the arrangement of its atoms, particularly electrons
8. energy-total kinetic energy and potential energy of an object
9. energy- energy an object had due to its position
12. device that reverses the current through an electric motor
14. a loop or coil of a wire carrying a current
16. needs a complete, closed, continuous path w/a source of electrical energy in order to keep flowing
19. an electric current produces a magnetic field
21. current- The current is the same resistor
