Ellie made an electromagnet with wire, a nail, and a 2.5-volt battery. The electromagnet attracted a paper clip from 2 inches away.

are you sure

Yes, decreasing the number of coils around the nail will make the electromagnet weaker, as there will be fewer turns of wire carrying current to produce the magnetic field.
