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… Continue Reading

Simulation: How emf is generated

This simulation is really more of an animation that allows students to apply Fleming’s left hand rule on a line of electrons along a conductor cutting a magnetic field in order to appreciate how emf is generated.

EMF of A.C. Generator

For my students to discuss. Please leave your answer and explanation in the comments below. Options are: A. $$V_0$$ (peak voltage) B. $$\frac{V_o}{\sqrt{2}}$$ C. Zero D. None of the above

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… Continue Reading

Using a datalogger to measure induced emf

This video tutorial is a guide for next week’s practical for CG18/12.
