SUMMARY

The discussion focuses on calculating the voltage and current generated by a magnet passing through a coil, utilizing parameters such as magnet strength, speed, number of coils, and coil area. The key equation mentioned is the inductance formula, L=(N^2/l)(μ/l)(A/l), which can be manipulated to derive the desired electrical outputs. Participants emphasize the importance of theoretical calculations versus experimental validation in achieving accurate results. Understanding these principles is crucial for effectively applying electromagnetic induction in practical scenarios.

PREREQUISITES
  • Understanding of electromagnetic induction principles
  • Familiarity with the inductance formula L=(N^2/l)(μ/l)(A/l)
  • Knowledge of basic electrical concepts such as voltage and current
  • Experience with coil design and magnet properties
NEXT STEPS
  • Research Faraday's Law of Electromagnetic Induction
  • Explore the relationship between coil turns and induced voltage
  • Learn about the effects of coil area on inductance
  • Investigate practical experiments to validate theoretical calculations
USEFUL FOR

Electrical engineers, physics students, and hobbyists interested in electromagnetic applications and coil design will benefit from this discussion.

Hello,

I need a calculation that can tell me how many Volts and Amperes a magnet passing through a coil will produce if you input the magnet strength, speed, number of coils, coil area etc...

Is there a common calculation I have missed for theoretically working this out? Or do you have to undergo experimentation?

If anybody knows a way of doing this, passing it on would be so very helpful.

Thank you

if you know the Inductance...

You manipulate this equation I would assume.

L=(N^2/l)(u/l)(A/l)
