About This Experiment
An AC generator works by rotating a coil in a magnetic field. The induced EMF follows EMF = NBAω sin(ωt), where N is the number of turns, B is magnetic field strength, A is coil area, and ω is angular frequency. This produces the characteristic sine wave of alternating current.
The peak EMF occurs when the coil is perpendicular to the magnetic field lines and moving fastest through them. The RMS (root mean square) voltage is peak voltage divided by √2, which represents the effective voltage for power calculations in AC circuits.
