Figure shows a straight wire of length a carrying a current `I`. What is the magnitude of magnetic field induction produced by the current at P, which is lying at a perpendicular distance a from one end of the wire.

Text Solution

Verified by Experts

The correct Answer is:
`(sqrt(2mu_(0)i))/(8pil)`
`B = (mu_(0))/(4pi) (I)/(l) [sin0^(@) + sin 45^(@)]=(mu_(0))/(4pi) (I)/(l) xx (1)/sqrt2`
`B =(sqrt2mu_(0)I)/(8pil)`
