Q. No.Initially plane of a coil is parallel to the uniform magnetic field \(B\). If in time \(\Delta t\) the coil is perpendicular to the magnetic field, then charge flows in \(\Delta t\) depends on this time as:
1. \(\propto \Delta t\)
2. \(\propto \frac{1}{\Delta t}\)
3. \(\propto (\Delta t)^0\)
4. \(\propto (\Delta t)^{2}\)
1. \(\propto \Delta t\)
2. \(\propto \frac{1}{\Delta t}\)
3. \(\propto (\Delta t)^0\)
4. \(\propto (\Delta t)^{2}\)
