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 ϕi. The magnetic flux through the area of the circular coil area is given by ϕo. Which of the following option is correct?
a. ϕi=ϕo
b. ϕi>ϕo
c. ϕi<ϕo
d. ϕi=−ϕo
