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.

Phase Difference Simulation

I created this simulation for use later this semester with my IP4 classes, to illustrate the concept of phase difference between two oscillating particles.

Update (26 August 2020): I have also created a GeoGebra app to demonstrate the same principle.

Simulation for Gravitational Field Strength and Potential

This simulation allows students to observe the variation of gravitational field strength and potential between two masses. Field strength is shown as vectors whereas potential is shown as scalar values on a plot. The resultant field strength and potential are shown in red.

Internal Resistance and Maximum Power Theorem

I’ve created this simulation to demonstrate the effect of an internal resistance due to a cell on the potential difference and current of an external load.

One can also vary the internal resistance and external resistance to observe the maximum power theorem. The theorem states that for a given finite internal resistance, one can obtain the maximum external power only when the resistance of the load is equal to the internal resistance of the source.
