Question

Why doesn Lenz's law happen? I understand that it creates a current that provided a magnetic field such that it opposes change in magnetic flux, and that energy of a moving object is converted into elevtrical energy of current flowing through a whire, so please DO NOT explain all that or Faradays law which is just the math behind Lenz's law. i just want to know why like whats happening on the most fundamental level, the math describes whats happening but why?

Answer 1

Lenzs law is based on the law of conservation of energy

Now let us think a conductor plate and a conducting current loop

Now let us generate magnetic field by sending a current through

The loop. As this magnetic field lines are cut by the conductor plate then

This drives electrons present the plate so current increases and also total magnetic field also

Increases. If this happens then we can produce infinite amount of free energy so, as this is not possible

Then current in the plate should be opposite. This is like Newton s third law action and reaction should be opposite to each other.
