Simulation: Faraday's Law of Induction

This simulation traces the flux linkage and corresponding emf generated by a rectangular coil rotating along an axis perpendicular to a uniform magnetic field. One is able to modify the angular frequency to see the effect on the frequency and peak emf generated.

Newton's Nightmare

This demonstration is called Newton's nightmare because it involves the slow dropping of a magnet that seems to be inconsitent with gravitational acceleration. Using the "CFILE" structure, we can explain how the magnet moves much slower in a metal pipe than when it is undergoing free fall (as in the PVC pipe, which serves as
