Test the electromagnet by placing the nail near the safety pins/ thumbtacks. 4. Observe what happens. How many safety pins/thumbtacks did the magnet attract? 5. Disconnect the wires. Connect/ add another dry cell to the first dry cell. Repeat procedure numbers 2 and 3. 6. Observe what happens. Record the number of safety pins/ thumbtacks attracted to the magnet. 7. Again, disconnect the wires before adding another dry cell to the setup. Repeat procedures 2 and 3. Record the number of safety pins/ thumbtacks that are attached to the magnet. 7
