As the magnetic monopole does not exist, thus magnetic field lines form closed loops.So the number of field lines going out through the closed surface is equal to number of field lines coming in. Hence magnetic flux linked with a closed surface is always zero.
Where θ = angle made by the lines of force with the normal to the surface
Case:-(i) If θ is acute:- This is the case when magnetic line of force comes out of the surface. In such a cos θ is positive. so, Magnetic flux is positive.
case:-(ii)If θ is obtuse:- This is the case when magnetic line of force enters a surface. In this case a cos θ is negative. so, Magnetic flux linked with the surface is negative.
case:- (iii)If θ = 90⁰:-This case when the line of force is parallel to the surface. since cos θ,in this case 0, so, Magnetic flux linked with the surface is also zero.
