Magnetism & Electricity (2 magnets - Field)

Click For Summary
SUMMARY

The discussion focuses on calculating the output voltage for a coil in an axial generator or alternator using Faraday's Law of Electromagnetic Induction. The setup includes two magnets with a maximum magnetic field strength of 13200 Gauss positioned on opposing sides of the rotor, with the coil situated on the stator. The effective magnetic flux density (Br) to be used in calculations is influenced by the geometry of the setup and the desired tolerances for accuracy.

PREREQUISITES
  • Understanding of Faraday's Law of Electromagnetic Induction
  • Knowledge of magnetic field strength and units (Gauss/Tesla)
  • Familiarity with axial generator and alternator design principles

I am trying to calculate the output voltage for 1 coil in an axial generator/altenator

I have 2 magnets with Br Max 13200 Gauss on opposing sides of the rotor (N-S facing), The coil is between them on stator. Using faradays equations what is the effective Br (Gauss/Tesla) that should be used.

Thanks

... should be used to achieve what aim?

Oh you mean, what approximate value should you use for B in Faraday's Law?
That will depend on the exact geometry of your setup - which determines the field characteristics - and the tolerances you want to work with (which determines how much hand-waving you get to use.)

You could, I guess, use a pole model for the magnets to predict the actual field through the loop at each angle?
