Question

If you used the 3-battery pack and the iron nail, and an 80-loop coil of wire, how many paper clips would you predict the electromagnet would pick up? Explain why.

Electromagnets have a wide range of uses, from the MRI machines used in hospitals to remote-control toy cars to many appliances in your home. They vary in strength from very weak but sensitive electromagnets used to detect other magnets or electric currents to the huge research instruments used here at the Magnet Lab.
