  3. It remains constant
  4. It stops flowing

Questions & Step-by-Step Solutions

If the magnetic field through a loop is increased uniformly, what happens to the induced current in the loop?
  • Step 1: Understand that a loop of wire can have a magnetic field passing through it.
  • Step 2: Recognize that when the magnetic field through the loop increases, it changes the magnetic flux (the amount of magnetic field passing through the loop).
  • Step 3: Remember Lenz's law, which states that the induced current will flow in a direction that opposes the change in magnetic flux.
  • Step 4: Since the magnetic field is increasing, the induced current will flow in a direction that creates a magnetic field opposing the increase.
  • Step 5: Conclude that the induced current will flow in the opposite direction to the increase in the magnetic field.
  • Electromagnetic Induction – The process by which a changing magnetic field induces an electromotive force (EMF) and consequently a current in a conductor.
  • Lenz's Law – A principle stating that the direction of induced current is such that it opposes the change in magnetic flux that produced it.
