What is the direction of the induced current when the magnetic field through a loop is increasing?
Clockwise
Counterclockwise
No current
Depends on the field strength
According to Lenz's law, the induced current will flow in a direction that opposes the change in magnetic flux. If the magnetic field is increasing, the induced current will flow counterclockwise.

Q: What is the direction of the induced current when the magnetic field through a loop is increasing?
Solution: According to Lenz's law, the induced current will flow in a direction that opposes the change in magnetic flux. If the magnetic field is increasing, the induced current will flow counterclockwise.
Steps: 5
Step 1: Understand that a magnetic field can change over time.
Step 2: Know that when the magnetic field through a loop increases, 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: Since the magnetic field is increasing, the induced current will try to create a magnetic field that opposes this increase.
Step 5: Determine the direction of the induced current: if the magnetic field is increasing into the loop, the induced current will flow counterclockwise to create a magnetic field out of the loop.
