Two similar circular co-axial loops carry equal currents in the same direction. If the loops be brought nearer, the currents in loops
A
Decreases
B
Increases
C
Remains same
D
Different in each loop
Answer
Decreases
Explanation
Solution
AS the loops are brought closer the magnetic flux linked with them increases. An emf is induced in each loop which opposes the change in flux. So the current in each loop decreases.
