1. Explain what it means when we say a substance is magnetic. 2. Discuss the relationship between electric and magnetic fields. 3. Before you begin your lab, you need to form a hypothesis that reflects which material, voltage, and number of winds you think will produce the strongest electromagnet. Record your hypothesis as an if-then statement. 4. Record your data for each trial. Size of Wire Gauge Material of Wire Voltage Number of Winds Resulting Paper Clips Picked Up Trials 1 Trials 2 Trials 3 Trials 4 Trials 5 5. Review your data. Did your experiment prove or disprove your hypothesis
