Question

Which change could increase the strength of an electromagnet choose the correct answer
1. Increasing the electric current.
2. Removing the iron core.
3. Shortening the wire.
4. Turning off the power.

GPT-5 mini · Answer

1. Increasing the electric current.

Explanation: The magnetic field of an electromagnet is stronger with more current (and more coil turns and a ferromagnetic core). Removing the iron core or turning off the power would weaken it; shortening the wire usually reduces the number of turns and would also weaken it.
