which of these situations would generate electrical current in a wire? check all that apply. moving a magnet into a solenoid moving a magnet out of a solenoid holding a magnet steady inside a solenoid holding a solenoid steady outside a magnet moving a solenoid in a magnetic field

Answer

Brief Explanations:

According to Faraday's law of electromagnetic - induction, an electromotive force (emf) and thus an electric current is induced in a wire when there is a change in magnetic flux through the wire - loop (solenoid in this case). Moving a magnet into or out of a solenoid changes the magnetic flux through the solenoid. Moving a solenoid in a magnetic field also changes the magnetic flux through the solenoid. Holding a magnet steady inside a solenoid or holding a solenoid steady outside a magnet does not change the magnetic flux.

Answer:

  • moving a magnet into a solenoid
  • moving a magnet out of a solenoid
  • moving a solenoid in a magnetic field
