What happens to the induced current in a closed loop if the magnetic field through the loop is increasing?
The induced current flows in a direction to oppose the increase
The induced current flows in the same direction as the increase
The induced current becomes zero
The induced current fluctuates
According to Lenz's law, the induced current will flow in a direction that opposes the increase in magnetic flux.

Q: What happens to the induced current in a closed loop if the magnetic field through the loop is increasing?
Solution: According to Lenz's law, the induced current will flow in a direction that opposes the increase in magnetic flux.
Steps: 6
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.
