A circular loop of radius `R` , carrying `I`, lies in `x- y` plane with its origin . The total magnetic flux through ` x-y` plane is

A

(a) directly proportional to `I`

B

(b) directly proportional to `R`

C

( c) directly proportional to `R`

D

(d) zero

Text Solution

Verified by Experts

The correct Answer is:
D
The magnetic lines of force created due to current be in such a way that on `x-y` plane these lines will be perpendicualr. Further, these lines will be in circular loops. The number of lines moving douwnward in `x-y` plane. Therefore, the net flux will be zero. One such magnetic line is shown in Fig. S3.81.
`:.` (d) is the correct option.
