Find the magnetic field at `P` due to the arrangement shown
.

A

`(mu_(o)i)/(sqrt2 pi d)(1 - (1)/(sqrt2)) ox`

B

`(2mu_(o)i)/(sqrt2 pi d) ox`

C

`(mu_(o)i)/(sqrt2 pi d) ox`

D

`(mu_(o)i)/(sqrt2 pi d) (1 + (1)/(sqrt2)) ox`

Text Solution

Verified by Experts

The correct Answer is:
A
`B = 2[mu_(o)/(4pi).(i)/(d//sqrt2)] (sin 90^(@) - sin 45^(@))`
`B = (mu_(o)i)/(sqrt2 pi d)(1 - (1)/(sqrt2)) ox`
