Question

craig is modeling the discovery of electromagnetism. which procedure should he use? moving a magnet into a coil of wire in a closed circuit moving a magnet into a coil of wire in an open circuit bringing a compass near a wire that has no electric current bringing a compass near a wire that has an electric current

Explanation:

Electromagnetism is demonstrated when an electric - current carrying wire creates a magnetic field. A compass can detect this magnetic field. A wire without current has no magnetic effect related to electromagnetism. Moving a magnet into a coil is related to electromagnetic induction, not the discovery of electromagnetism as such. For electromagnetism discovery, showing the magnetic effect of an electric current is key. A closed or open circuit with a moving magnet is about induction.

Answer:

bringing a compass near a wire that has an electric current
