Question Melissa and Cassidy built the electromagnet pictured above. They coil a copper wire around a bolt and connected the wire to both ends of a battery. When they tested it, it could pick up 3 paper clips. Their teacher challenged all groups to pick up a minimum of 10 paper clips. What could they do to increase the number of paper clips their electromagnet picks up?(1 point) Responses increase the number of loops of wire around the nail increase the number of loops of wire around the nail make the wire longer make the wire longer remove the nail from the center of the wire remove the nail from the center of the wire spread the loops of wire apart on the nail so they do not touch
To increase the number of paper clips their electromagnet picks up, Melissa and Cassidy could increase the number of loops of wire around the bolt. By adding more loops, there will be more wire to generate magnetic field and thus increase the strength of the electromagnet.
