SUMMARY

The discussion focuses on the operation of a magneto, specifically addressing the phenomenon of voltage spikes during the collapse of the magnetic field. This spike in voltage is attributed to Faraday's Law of Electromagnetic Induction, which states that a time-varying magnetic field induces an electric field. The key takeaway is that the significant change in magnetic flux during the collapse of the magnetic field is the primary reason for the induced voltage spike.

PREREQUISITES
  • Understanding of Faraday's Law of Electromagnetic Induction
  • Basic knowledge of magnetic fields and flux

Hey guys, I was wondering how a magneto works exactly?

I have been reading a lot, but I do not understand why the voltage spikes when the magnetic field collapses. Any help?

The voltage spikes when The B field collapses because we have a big change in magnetic flux. Faradays law. A time varying B field induces an E field.
