there is no change in the magnetic flux through coil C 1 and the current in coil C 1 drops to zero. When the key is released, the current in C 2 and the resulting magnetic field decreases from the maximum value to zero in a short time. This results in a decrease in magnetic flux through coil C 1 and hence again induces an electric current in ...
