Questions & Step-by-Step Solutions

Which of the following is a consequence of Lenz's law?
  • Step 1: Understand what Lenz's law is. It says that when a magnetic field changes, it creates an electric current in a loop of wire.
  • Step 2: Know that this induced current flows in a direction that opposes the change in the magnetic field.
  • Step 3: Realize that this means if the magnetic field is increasing, the induced current will flow in a direction that tries to decrease it.
  • Step 4: Conversely, if the magnetic field is decreasing, the induced current will flow in a direction that tries to increase it.
  • Step 5: Conclude that the consequence of Lenz's law is that the induced current always works against the change in magnetic flux.
