5 Electricity & Magnetism

Exploring RC time constants with oscilloscope

The time constant is much smaller as the gap in the capacitor is made wider.

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).
