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)%0D%0AResponses%0D%0A%0D%0Aincrease the number of loops of wire around the nail%0D%0Aincrease the number of loops of wire around the nail%0D%0A%0D%0Amake the wire longer%0D%0Amake the wire longer%0D%0A%0D%0Aremove the nail from the center of the wire%0D%0Aremove the nail from the center of the wire%0D%0A%0D%0Aspread the loops of wire apart on the nail so they do not touch
To increase the number of paper clips their electromagnet can pick up, Melissa and Cassidy can do the following:
1. Increase the number of loops of wire around the nail.
2. Make the wire longer.
3. Spread the loops of wire apart on the nail so they do not touch.
However, it seems that there are duplicate responses in the provided options. The correct selection should include:
- Increase the number of loops of wire around the nail.
- Make the wire longer.
- Spread the loops of wire apart on the nail so they do not touch.
These actions will increase the strength of the magnetic field produced by the electromagnet and thus allow it to pick up more paper clips.
