Assertion (A): When plane of coil is perpendicular to magnetic field, magnetic flux linked with the coil is minimum, but induced e m f is zero Reason ( R ) : ϕ = n A B cos θ and e = d ϕ d t

Step-by-step solution

According to faraday's law of induction, induced emf   e = - d ϕ d t ϕ   is the magnetic flux linkage with the coil it is defined as, ϕ = B → · ∆ s →   or ϕ = B ∆ s cos θ ,   here, θ   is the angle between the magnetic field vector and area vector, therefore, when θ = 0 ° ,   ϕ   has maximum value and for θ = 90 ° ,   ϕ   has minimum value. Thus, when plane of coil is perpendicul
