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?
Solution
As, magnetic field lines forms a closed loop, hence each line from circular area will pass through outer area
in opposite direction hence $\phi$<sub>i</sub> = - $\phi$<sub>0</sub>.
