Lenz's Law Diagram: Understanding the Principles and Applications

In summary, the diagram illustrates Lenz's Law, which explains the relationship between a moving magnet and a coil. The change in the magnet's field induces a current in the coil that opposes the change, in order to maintain a constant magnetic flux. This is due to the conservation of energy. When the magnet is moving towards the coil, the field increases and when it is moving away, the field decreases. This can be seen in the diagrams, where the induced field is in the same direction as the magnet's field when it is moving away and in the opposite direction when it is moving towards. This also applies in cases where a permanent magnet is used, and the induced field tries to "reinforce" the original field to maintain the constant

I got to this string late, but your question is not too clear.
Maybe it will help you to say that you have to apply a force to the magnet to push to toward the loop. This increases the energy in the system.

And why when the energy is released (when we'll pull out the permanent magnet) the electrons want to increase the energy again, by following the permanent magnet's force lines?
