Introduction part II - Hypothesis Based on the procedure, draw sketches of what you think you will see when you pour the iron filings on the paper in each situation. Be sure to say why you think it will look the way it does, and support that with external references. Materials: Two bar magnets, one horseshoe magnet, iron filings, sheet of paper, compass Procedure: 1. Cover the bar magnet with the sheet of acetate (or paper). Carefully sprinkle the iron filings onto the sheet of acetate around the bar magnet and look for any patterns formed by the iron filings, especially near the poles of the magnet. Sketch any patterns that you find (these sketches will be your observations). 2. Use the compass to indicate the direction of the field around the space above the bar magnet. Draw a picture of the magnetic field around the magnet. 3. Repeat the procedure for the following cases: i) like poles of the bar magnets close to each other ii) opposite poles of the bar magnets close to each other ii) of the bar magnets side-by-side v) horseshoe magnet by itself one arrangement of at least one horseshoe magnet and one bar magnet of your choice
