Two infinitely long wires each carrying ...

Two infinitely long wires each carrying current I along the same direction are made into the geometry as shown in the figure. The magnetic field at the point P is

A

`(mu_(0) I)/( pi r)`

B

`(mu_(0) I)/(r ) ((1)/(pi) + (1)/(4))`

C

Zero

D

`(mu_(0) I)/(2pi r)`

Text Solution

Verified by Experts

The correct Answer is:
D
`B = (mu_(0) I)/(4pi r) + (mu_(0) I)/(4pi r) = (mu_(0) I)/(2pi r)`
