    Law Lenz's law
Click For Summary
The discussion focuses on Lenz's Law and its application in understanding induced currents in coils due to changing magnetic fields. When a magnet moves towards or away from a coil, the magnetic field through the coil changes, resulting in induced currents that create opposing magnetic fields. The key principle is that the induced current acts to maintain a constant magnetic flux through the coil, opposing any changes. Participants clarify that the strength of the magnetic field decreases with distance from the magnet, and the induced field's direction depends on whether the external field is increasing or decreasing. Overall, the conversation emphasizes the conservation of energy and the behavior of magnetic fields in response to motion.

Anybody know this?

can you tell me please? thank you.

I want to say that always the electrons tend to have lower energy level and also I couldn't understand how do the field is increased when their magnetic field is opposite of the permanent magnet's field.
Noone knows this?

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.

Why you think that it'll increase the energy, when the electrons oppose of the increase of the magnetic field? That's what I am asking.

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?
