Electromagnetic Induction

This demonstration exhibits the relationship between induced EMF and magnetic flux. In the apparatus, we have a rotating disk which has magnets placed on it, a Hall probe, and two solenoids with different number of turns. As the magnets are swept from beneath the sensors, the solenoids register the rate of change of flux while the Hall probe directly measures the flux. These variables are displayed on simultaneous graphs, all in real time.
