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 $\displaystyle \phi_{\mathrm{i}}$. The magnetic flux through the area of the circular coil area is given by $\displaystyle \phi_0$. Which of the following option is correct ?
Official answer
(4)
$\displaystyle \phi_{\mathrm{i}}=-\phi_0$
