Questions & Step-by-Step Solutions

What happens to the induced EMF if the speed of a conductor moving through a magnetic field is doubled?
  • Step 1: Understand that EMF (Electromotive Force) is induced when a conductor moves through a magnetic field.
  • Step 2: Know that the induced EMF depends on the speed of the conductor moving through the magnetic field.
  • Step 3: If the speed of the conductor is doubled, it means the conductor is moving faster through the magnetic field.
  • Step 4: When the speed increases, the rate at which the magnetic field lines are cut by the conductor also increases.
  • Step 5: Since the rate of change of magnetic flux increases, the induced EMF will also increase.
  • Step 6: Specifically, if the speed is doubled, the induced EMF will also double.
