Two long straight wires are set parallel...

Two long straight wires are set parallel to each other. Each carriers a current `i` in the same direction and the separation between them is `2r`. The intensity of the magnetic field midway between them is

A

Zero

B

`(mu_(0)i)/(4piR)`

C

`(mu_(0)i)/(2piR)`

D

`(mu_(0)i)/(piR)`

Text Solution

Verified by Experts

The correct Answer is:
D
`B=(mu_(0)i)/(2piR)+(mu_(0)i)/(2piR)=(mu_(0)i)/(piR)`
