Activity:
ELECTROMAGNET This activity is taken from Janice VanCleave Physics for Every Kid, John Wiley and Sons, 1991 Problem: How can we show that an electric current produces a magnetic field? Hypothesis: We think if ____________________________________________ ________________________________________________________________then ____________________________________________________________________ ____________________________________________________________________. Materials: 1 yard of wire, battery, long iron nail, paper clips Procedure: 1. Wrap the wire tightly around the nail, leaving about 3 inches of free wire on each end. 2. Strip the insulation off both ends of the wire. 3. Secure one end of the wire to one pole of the battery. 4. Touch the free end of the wire to the other battery pole while touching the nail to a pile of paper clips. 5. Lift the nail while keeping the ends of the wire on the battery poles. 6. When the nail starts to feel warm, disconnect the wire end you are holding against the battery pole. Observations: Draw a picture as well (if possible). _________________ ____________________________________________________________________ ____________________________________________________________________.
