The magnetic field perpendicular to the plane of a loop of area 0.1 m 2 is 0.2 T. Calculate the magnetic flux through the loop.

Area vector of any surface is perpendicular to the surface and if surface is a part of a closed surface then area vector is directed outside the surface. As the given magnetic field is perpendicular to the plane of loop, the area vector and magnetic field make 0 ° with each other. Magnetic flux ϕ by a magnetic field B → from any surface having area vector A → is defined as: ϕ = B → . A → = B A cos θ , where θ is the angle between B → and A → , B and A are the magnitudes of magnetic field and area vector. Given, B = 0 . 2 T , A = 0 . 1 m 2 and θ = 0 ° . ϕ = 0 . 2 × 0 . 1 × cos 0 ° ϕ = 0 . 02 Wb
