Electromagnetic Feedback Loop

The feedback loop can be summarized in a list, including phenomena belonging to each part of the loop:

charged particles generate electric and magnetic fields the fields interact with each other changing electric field acts like a current, generating 'vortex' of magnetic field

Faraday induction: changing magnetic field induces (negative) vortex of electric field

Lenz's law: negative feedback loop between electric and magnetic fieldsfields act upon particles

Lorentz force: force due to electromagnetic field

electric force: same direction as electric field

magnetic force: perpendicular both to magnetic field and to velocity of charge particles movecurrent is movement of particles particles generate more electric and magnetic fields; cycle repeats
