MCQ
Two identical coaxial circular loops carry a current $i$ each circulating in the same direction. If the loops approach each other
  • the current in each will decrease
  • B
    the current in each will increase
  • C
    the current in each will remain the same
  • D
    the current in one will increase and in other will decrease

Answer

Correct option: A.
the current in each will decrease
a
Source flux $\phi_{1}$ increases so induce flux will oppose the source flux that's why it will produce. Current in opposite direction to main current. So current in each will decrease
