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
