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

Answer

Brief Explanations:

  • Moving a magnet into a coil of wire in a closed circuit is related to electromagnetic induction (Faraday's law), not the discovery of electromagnetism.
  • Moving a magnet into a coil of wire in an open circuit won't show the key aspect of electromagnetism.
  • Bringing a compass near a wire with no current won't demonstrate electromagnetism as there is no magnetic effect from the wire.
  • Bringing a compass near a wire with an electric current shows that an electric current can produce a magnetic field, which is the discovery of electromagnetism (Oersted's experiment).

Answer:

bringing a compass near a wire that has an electric current
