Consider following coils each of one turn carrying current `I`. The magnitude of the magnetic induction at `X,Y,Z` are `B_(1),B_(2)` and `B_(3)` respectively. Then (assume side of square to be same in each case)

A

`B_(3)gtB_(1)gtB_(2)`

B

`B_(2)gtB_(3)gtB_(1)`

C

`B_(2)gtB_(1)gtB_(3)`

D

`B_(1)gtB_(2)gtB_(3)`

Text Solution

Verified by Experts

The correct Answer is:
A
`B_(3)` should be greater than `B_(1)`, because distance of Centre from current is lesser in this case. `B_(2` is obviously least.
