SUMMARY

The calculation of induced electromotive force (emf) in a dynamo can be derived using Faraday's Law of Electromagnetic Induction. Specifically, the induced emf is proportional to the rate of change of magnetic flux through the coil. To translate the change of the rotating coil's area into an algebraic equation, one must consider the coil's angular velocity and the magnetic field strength. The formula for induced emf is given by ε = -dΦ/dt, where Φ represents the magnetic flux.

PREREQUISITES
  • Understanding of Faraday's Law of Electromagnetic Induction

I want to know how I can calculate the induced emf in the dynamo, I don't know how I can translate the change of the rotating coil's area into an algebraic equation. Thanks in advance.
