A current of 6 A passes through the wire...

A current of 6 A passes through the wire shown in the figure. Find the magnitude of magnetic field at point C. The radius is 0.2 m.
`(mu_(0)=4pixx10^(-7)TmA^(-1))`

Text Solution

Verified by Experts

1. I = 6A, a = 0.2m, `theta=2pi-pi/2=(3pi)/2`
`mu_(0)=4pixx10^(-7)TmA^(-1)`
2. `B=(mu_(0)I(2pi-theta))/(4pia)=(4pixx10^(-7)xx6((3pi)/2))/(4pixx0.2)`
`thereforeB=1.41xx10^(-5)T`
