Two identical coaxial circular loops carry current i each circulating in the clockwise direction. If the loops are approaching each other, then:
The net current in each loop increases.
The net current in each loop remains the same.
The net current in each loop decreases.
The net current in one loop increases but it decreases in the other.
The correct option is C The net current in each loop decreases.
According to Lenz's law, the induced current will appear in such a direction that it opposes the changes in the magnetic flux in the coil. When the two loops approach each other, the induced current will be in anti-clockwise direction. Therefore, the net current in both the loops would decrease.
