Question: Lenz\'s law states that the direction of induced current is such that it opposes what?

Options:

  1. The change in magnetic flux
  2. The flow of electric current
  3. The resistance in the circuit
  4. The applied voltage

Correct Answer: The change in magnetic flux

Solution:

Lenz\'s law states that the direction of induced current will oppose the change in magnetic flux that produced it.

Questions & Step-by-Step Solutions

Lenz's law states that the direction of induced current is such that it opposes what?
Correct Answer: the change in magnetic flux
  • Step 1: Understand that Lenz's law is about induced current in a conductor.
  • Step 2: Know that induced current is created when there is a change in magnetic field around the conductor.
  • Step 3: Recognize that 'magnetic flux' refers to the amount of magnetic field passing through a surface.
  • Step 4: Realize that Lenz's law states the induced current will flow in a direction that opposes the change in magnetic flux.
  • Step 5: Conclude that if the magnetic flux is increasing, the induced current will flow in a direction to decrease it, and if it is decreasing, the induced current will flow to increase it.
  • Lenz's Law – Lenz's law describes how induced currents in a conductor oppose the change in magnetic flux that created them, ensuring conservation of energy.
