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.

Verified by Experts

The direction of magnetic induction due to current through the portion XO and OY at P are indicated as `vecB_1` and `vecB_2`, Figure.

`:.` Total magnetic induction at P,
`vecB_p=vecB_1+vecB_2` and `|vecB_p|=sqrt(B_1^2+B_2^2)`
or `vecB_p=(mu_0)/(4pi)i/l(sin90^@+sin0^@)hatj`+`(mu_0)/(4pi)i/lxx(sin 90^@+sin0^@)hati`
or `|vecB_p|=(mu_0)/(4pi)i/lsqrt2=10^-7xx(5*0)/(0*35)xxsqrt2`
`=2*0xx10^-6T`
