A closed loop is held stationary in the magnetic field between the north and south poles of two permanent magnets held fixed. Can we hope to generate current in the loop by using very strong magnets?

## Answer

No, there will not be any current in the loop as the loop is stationary in the magnetic field. The current gets induced only when there is change in the flux linked with the coil, Whatever be the strength of the magnetic field
A closed loop moves normal to the constant electric field between the plates of a large capacitor. Is a current induced in the loop
(i) When it is wholly inside the region between the capacitor plates
(ii) When it is partially outside the plates of the capacitor?
The electric field is normal to the plane of the loop.
⟹ Since, the electric field is constant between the plates, no displacement current and no magnetic field between it. Hence no change in the magnetic flux linked with the coil if it is moving wholly inside the region or it is partially outside the plates.
