In 1835, Mr. Lenz had formulated that electromagnetically induced current flows in such direction that the action of magnetic field setup by it tends to oppose the cause which produce it.According to his name, this law is known as Lenz’s Law.
Now we describe the direction of induce current.
From the figure 1, It is seen that when
And when the magnet is withdrawn from the coil as shown in fig-2, same induced current flows in the clockwise direction in the coil and this induced current makes the face of the coil a S-pole.
Therefore,
