You are provided with a bar magnet, a coil and a galvanometer. Describe the activity with the help of these to show that :

(i) a current is induced in the coil only when magnetic field lines through it change

(ii) induced current lasts till the change in magnetic field is taking place

(iii) direction of induced current depends on whether magnetic field lines through the coil are increasing or decreasing

(iv) induced current is the highest when magnetic field and motion of the coil are perpendicular to each other. Draw diagram for the setup.
