An infinite long wire lying along the \(Y\)-axis, is carrying a current \(I\) as shown in the figure. The magnetic flux through a circular loop of radius \(R\) in the \(x y\)-plane is [assume, \(\mu_0=\) magnetic in free space permeability]
- A \(\frac{\mu_0 l}{2 \pi R}\)
- B \(\mu_0 / R\)
- C \(\frac{\mu_0 l}{\pi R^2}\)
- D None of these
Answer & Solution
Correct Answer
(D) None of these
Step-by-step Solution
Detailed explanation
The magnetic field at point due to a current carrying straight conductor of infinite length is \(B=\frac{\mu_0 I}{2 \pi R}\) The magnetic flux through circular loop around conductor in \(x y\)-plane is \(\phi_B=B A=\frac{\mu_0 I}{2 \pi R} \times \pi R^2=\frac{\mu_0 I R}{2}\)
