Questions & Step-by-Step Solutions
What is the direction of the induced current when the magnetic field through a loop decreases?
Step 1: Understand that a magnetic field can pass through a loop of wire.
Step 2: Recognize that when the magnetic field decreases, it means there is less magnetic force acting 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 the magnetic field.
Step 4: Since the magnetic field is decreasing, the induced current will try to create a magnetic field that opposes this decrease.
Step 5: Determine the direction of the induced current: if the magnetic field is decreasing, the induced current will flow counterclockwise to create a magnetic field that points in the same direction as the original field.
