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.
