Question

Consider a circular coil of wire carrying constant current I, forming a magnetic dipole. The magnetic flux through an infinite plane that contains the circular coil and excluding the circular coil area is given by $\phi_i$. The magnetic flux through the area of the circular coil area is given by $\phi_0$. Which of the following option is correct?

Select the correct option:

$\phi_i=-\phi_0$

$\phi_{\mathrm{i}}<\phi_0$

$\phi_{\mathrm{i}}=\phi_0$

$\phi_{\mathrm{i}}>\phi_0$
