4. Row 1, Col 1 Why does a neutron not experience a force when inside of a magnetic field? What is because it’s neutral?

5. 1,2 What makes a substance magnetic, at the ATOMIC LEVEL? What is when atoms line up in the same direction throughout the material?

6. 1,3 What materials were needed to make an electromagnet? What is wire, a nail, and a battery?

7. 1,4 What’s one way to make an electromagnet stronger? What is by adding more coils, a more ferrous core, or adding more current?

8. 2,1 What happens if you reverse the direction of the current in an electromagnet? What the North and South Pole reverse?

9. 2,2 Which compass is correct? What is A?

10. 2,3 Which side of the floating magnet is North? What is side 2?

11. 2,4 Name at least 2 things that are effected by, or attracted, to a magnet. What is 1) another magnet, 2) a Compass, 3) current?

12. 3,1 Which direction is North? What is the left side, or side A?

13. 3,2 Which side is North? What is the right side, or side B?

14. 3,3 What is the direction of the magnetic force on the wire? What is out of the page?

15. 3,4 If the current was turned off, how would the force change? There is no force for STATIONARY charges.

16. 4,1 Which direction is the current flowing inside the wire? What is up?

17. 4,2 What direction does the magnetic field below wire 1? What is out of the page?

18. 4,3 Will these two wires attract or repel each other? What is attract!?

19. 4,4 What is the direction of the force? What is to the right?

20. 5,1 Which direction is the current flowing in the wire? What is down?

21. 5,2 What is the difference in a Generator and a Motor (hint: think in terms of electricity and work)? What is a motor produces work, and a generator uses work ?

22. 5,3 Which side of this magnet is North? What is the right?

23. 5,4 Explain why the Earth’s geographic North Pole is has to be the Earth’s magnetic South Pole? What is because compasses point towards the south end of a magnet?
