This is a vivid demonstration of the concept of mutual inductance. A function generator and audio amplifier drive current through

In this demonstration we exhibit the phenomena of magnetic braking. In the apparatus we have two metallic plates (one with

This demonstration exhibits the relationship between induced EMF and magnetic flux. In the apparatus, we have a rotating disk which

In this demonstration we measure the voltages across the resistor and the capacitor to investigate the time needed to discharge

Discovered by German physicist Heinrich Barkhausen in 1919, the Barkhausen effect is a name given to the noise which a

This demonstration exhibits the concept of motional emf. When a conductor is moved through a uniform magnetic field,
an emf
