A coil of \(N\) turns is placed in a magnetic field \(\vec{B}\) such that \(\vec{B}\) is perpendicular to the plane of the coil. \(B\) changes with time as \(B=B_0 \cos \left(\frac{2 \pi}{T} t\right)\) where \(T\) is time period. The magnitude of emf induced in the coil will be maximum at

Here, \(n =1,2,3,4, \ldots\)
