Two long straight wires, each carrying a current `I` in opossite directions asre separated by a distasnce `R`. The magnetic induction at a point mid way between the wire is

A

`(mu_(0)I)/(pir)`

B

`(2mu_(0)I)/(pir)`

C

`(mu_(0)I)/(2pir)`

D

zero

Text Solution

Verified by Experts

The correct Answer is:
B

`B=(mu_(0)I)/(2pi.r/2)+(mu_(0)I)/(2pi.r/2)=(2mu_(0)I)/(pir), ox`
