Questions
Two circular, and similar coaxial loops carry equal currents in the same direction. If the loops are brought nearer, what will happen?
a
Current will increase in each loop.
b
Current will decrease in each loop.
c
Current will remain same in each loop.
d
Current will increase in one and decrease in the other.
detailed solution
Correct option is B
When the loops are brought nearer, magnetic flux linked with each loop increases. Thus the current will be induced in each loop in a direction opposite to its own current in order to oppose increase in magnetic flux. This is in accordance with Lenz's law. So, the current will decrease in each loop.Talk to our academic expert!
