Cinema Classics: Electromagnetism: Electromagnets. A coil of wire connected to a dry cell is shown to attract iron weakly. When an iron core is placed inside the coil the attraction is greatly increased. Electromagnets are shown to work only when the current is on. Two D cells and electromagnet lift a man (Newton's Apple video).

Hysteresis of a iron-core toroid.

Sargent-Welch toroid.

The Sargent-Welch toroid is used to show a typical hysteresis curve of an inductor/transformer with a ferromagnetic core. When setting this demo up follow the schematic shown, however, values do not need to be exact in order to achieve very good results. This demo also works well with a broad range of frequencies (saw tooth signals are best), just adjust R3 to achieve the desired trace pattern.
