A very long wire carrying a current I = ...

A very long wire carrying a current `I = 5.0 A` A is bent at right angles. Find the magnetic induction at a point lying on a perpendicular to the wire, drawn through the point of hending at a distance `l = 35 cm` from it.

Text Solution

Verified by Experts

`vec(B_(0)) = vec(B_(1)) + vec(B_(2))`
or, `|vec(B_(0))| = (mu_(0) i)/(4pi l) sqrt(2) = 2.0 mu T`, (using 3.221)
