Questions & Step-by-Step Solutions
What happens to the induced current in a closed loop if the magnetic field through the loop is increasing?
Correct Answer: Induced current flows in a direction that opposes the increase in magnetic flux.
Step 1: Understand that a closed loop can have a magnetic field passing through it.
Step 2: Recognize that if the magnetic field strength is increasing, it means more magnetic lines are 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: Determine the direction of the increasing magnetic field (e.g., if it is increasing into the loop).
Step 5: Figure out the direction of the induced current that would create a magnetic field opposing the increase (e.g., if the magnetic field is increasing into the loop, the induced current will flow in a direction that creates a magnetic field out of the loop).
Step 6: Conclude that the induced current flows in a direction that opposes the increase in the magnetic field.
