A student set a compass on top of a wire not yet connected in a circuit. When she connected thewire to the positive side of the D-cell, the compass needle moved.Why did the compass needle change position when the circuit was closed?

A group of students from another class wanted to improve their electromagnet design. Startingwith the standard design that everyone used in class, they decreased the number of winds on thecore and added three more batteries. Then they tested their new design. Their electromagnetcould pick up more paper clips than the original design. They recorded the followingconclusion:
The fact that our modified electromagnet picked up more paper clips tells us thatless winds and more batteries are both ways to make an electromagnet stronger.
Evaluate this group’s investigation and explain to them why you agree or why you disagree withtheir conclusion.
