`ABCD` is a square of side `L`. A very long straight conductor carrying a current `i` passes through the vertex `A` of the square and is perpendicular to its plane. The minimum magnetic induction at a vertex of the square is

A

`(mu_(0))/(4pi)(2sqrt(2)i)/(L)`

B

`(mu_(0))/(4pi)(sqrt(2)i)/(L)`

C

`(mu_(0))/(4pi)(4sqrt(2)i)/(L)`

D

`(mu_(0))/(4pi)(2i)/(L)`

Text Solution

Verified by Experts

The correct Answer is:
2
`B=(mu_(0)i)/(2pir)` . The maximum distance of a vertex from the conductor is `sqrt(2)L`.
