when the magnetic induction varies linearly with time, the induced voltage is constant in alternating directions, thus varying as a square wave in sync with the input signal. why does a linear change in voltage create an induced steady volt output at the probe? Explain with the use of the proper equation.

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...
