Question

Juan makes an adjustment to an electromagnet that causes the electromagnet to lose some of its strength. What did Juan most likely do?

He reduced the number of loops in the wire.
He increased the number of loops in the wire.
He reduced the length of the wire.
He increased the length of the wire.

GPT-5 mini · Answer

He reduced the number of loops in the wire.

Reason: The magnetic field of an electromagnet is proportional to the number of turns (N) times the current (I) — B ∝ N·I. Fewer loops mean fewer turns, so the magnet becomes weaker.
