Question: What happens to the induced current in a closed loop if the magnetic field through the loop is increasing?

Options:

Correct Answer: The induced current flows in a direction to oppose the increase

Solution:

According to Lenz\'s law, the induced current will flow in a direction that opposes the increase in magnetic flux.

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.

Lenz's Law – Lenz's law states that the direction of induced current is such that it opposes the change in magnetic flux through the loop.
Induced Current – Induced current is the current generated in a conductor due to a changing magnetic field.
Magnetic Flux – Magnetic flux is the product of the magnetic field and the area through which it passes, and it can change over time.
