Question

Find the magnetic induction at point `O` if the current carrying wire is in the shape shown in the figure.
.
A. `(mu_(0)I)/(2R)`
B. `(mu_(0)I)/(2piR)`
C. `(mu_(0)I(pi^(2)+4)^(1//2))/(4piR)`
D. `(mu_(0)I(pi^(2)+4))/(4piR)`

Answer 1

Correct Answer - 3
`B_(1)=(mu_(0)i)/(4pir)+(mu_(0)i)/(4piR),B_(2)=(mu_(0)i)/(4R),B=sqrt(B_(1)^(2)+B_(2)^(2))`
