DO NOT put filings directly on magnet
  • This is a lab my son just did in second grade
  • We will extend the lab however by adding extra magnets.
  • Make sure that your magnets are true by first checking to see if N - S attract and N – N or S – S repel
  • Place the magnets on the table as indicated on the following pages and place the manila folder over it
  • Add iron filings, draw the pattern on your lab paper
  • Arrows () start at North and point towards South
  • Return filings to the shaker.
  • DO NOT put filings directly on magnet
