"I tested different size bolts and different amount of coils by hooking up a battery and seeing how many paper clips the electromagnet would pick up. I found out that a long bolt with the most coils made the strongest electromagnet. I chose this because I like learning about electricity. Electromagnets are important because they are used in lots of technology."
