  11. All magnets have the same strength.

  12. False. The strength of magnets vary.

  13. Unlike poles on a magnet attract.

  14. True. Unlike poles attract to one another.

  15. DAILY DOUBLE Magnets attract to pennies.

  16. DAILY DOUBLE False. Pennies do not contain the metal that attracts to magnets.

  20. False. Two similar poles don’t attract.

  21. Glass

  22. Not magnetic

  23. A magnet

  24. Definitely magnetic

  25. Iron

  26. Definitely magnetic

  27. DAILY DOUBLE Gold

  28. DAILY DOUBLE Not magnetic

  29. Plastic

  30. Not magnetic

  31. The strength of a magnet can ___________.

  32. Vary

  33. Electricity and ______________ are similar.

  34. Magnetism

  35. The north pole of a magnet will attract to the ___________________ of another magnet.

  40. increases

  41. Why does it take more washers to separate two magnets with no spacers in between them, than it does with 4 spacers?

  42. Because the magnetic force field is not being interrupted or broken when there are no spacers.

  43. DAILY DOUBLE Suppose you hold 2 magnets over 2 different nails. One attracts to the magnet, and the other one doesn’t~ Why?

  44. The nail that doesn’t attract is not made with a metal that attracts to a magnet.
