Problem

Consider a circular coil of wire carrying constant current II, 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 ϕi\phi_i. The magnetic flux through the area of the circular coil area is given by ϕo\phi_o. Which of the following option is correct? (1) ϕi=ϕo\phi_i = \phi_o (2) ϕi>ϕo\phi_i > \phi_o (3) ϕi<ϕo\phi_i < \phi_o (4) ϕi=−ϕo\phi_i = -\phi_o
