Question
凹
4x Mr. Smith challenged his students to create an electromagnet that will pick up more paper clips than anyone else in the class.
Timmy is very excited and begins to collect all of the necessary materials. He finds a D-cell battery, an iron nail, and a large roll of copper wire. What could Timmy do, using just these materials, to increase the strength of his electromagnet to pick up the maximum amount of paper clips?
4x
A cut the iron nail in half to use as the core
only attach the battery to one end of the nail
C
increase the number of coils of copper he puts around the nail
decrease the number of coils of copper wire he puts around the nail

To increase the strength of his electromagnet and pick up the maximum amount of paper clips, Timmy should:
**C. increase the number of coils of copper he puts around the nail.**
Increasing the number of coils of copper wire around the iron nail will enhance the magnetic field created by the current flowing through the wire. More coils mean a stronger magnetic field, which allows the electromagnet to pick up more paper clips. Additionally, it's important to ensure that the battery connection is secure and that the D-cell battery has sufficient charge to power the electromagnet effectively.
