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 
. The magnetic flux through the area of the circular coil area is given by 
. Which of the following option is correct?
