A
directly proportional to `I`
B
directly proportional to `R `
C
inversly proportional to `R`
D

Text Solution
Verified by Experts
The correct Answer is:
D
magnetic lines of force created due to current will be In such a way that on ` x - y ` plane these lines will be perpendicular . Further , these lines will be in circular loops. The number of lines moving downwards in `x - y ` plane . Therefore , the net flux will be zero . one such magnetic line is shown in the figure
