What type of items do magnets pick up?
EXPERIMENT 1: MAGNETS
EXPERIMENT 2: MAGNETIC FIELD
PROCEDURE: Put the bar magnet under a piece of paper. Sprinkle the filings on top of the paper. Move the magnet slowly. Draw the magnetic field configuration that appears.
EXPERIMENT 3 WHAT IS MAGNETIC? (use bar, logo or ring)
PROCEDURE: Test to see which items are magnetic and which are not. List them accordingly:
What kinds of materials are magnetic?
EXPERIMENT 4: MAGNETIC FORCE (1 logo, bar, ring magnets)
- Are all magnets of equal strength?
- Can you make a stronger magnet by sticking several magnets together?
- Will a magnet attract things through a sheet of paper?
Find out whether these items will "block" the magnetic force. Answer yes or no, and comment on your findings.
CONCLUSION: Why do you think magnets pick up only certain substances?
