2. This type of material allows electrons to flow through it

3. What is a conductor?

4. It is what happens when you get shocked

5. What is excess electrons jump from you to the object (or vice versa) to even out the charge?

6. It is what happens when a charged object is held next to a neutral one

7. What is the neutral object becomes polarized (by induction)?

8. The direction of the force between a piece of wool and styrofoam after rubbing them together

9. What is attraction?

10. The reason a charged object can attract a neutral one

11. What is “the neutral object becomes polarized, so the charged object attracts the near side more than it repels the far side (since it is farther away)?

12. The “I” in Ohm’s Law, and its units

13. What is current, amperes?

14. The current flowing through a 220 Ohm light plugged into the wall (110 V)

32. This can be created by moving charges

33. What is a magnetic field?

34. Moving magnets will create this

35. What is an electric field?

36. The magnetic field near a straight current- carrying wire looks like this

37. What is circular (around the wire)?

38. Where the magnetic poles of a coiled wire with an electric current are located.

39. What is on the top and bottom?

40. The direction of the force on a current- carrying wire, relative to the direction of the current and magnetic field lines

41. What is perpendicular?

42. It converts electrical energy into kinetic

43. What is a electric motor?

44. In a speaker the motion of the cone is caused by this

45. What is the varying force between the permanent magnet and electromagnet?

46. How does the force on the coil change if the current changes direction

47. What is it reverses?

48. A speaker can also be used as this, which produces electrical energy

49. What is a microphone?

50. The reason our motors only rotate in one direction

51. What is “the unsanded part of the coil prevents current from flowing when it would cause a force in the opposite direction”
