Portrait of Andre Ampere
Numéro d’image : 11827045
| Andre Marie Ampere (1775-1836),after a contemporary portrait in oils. A gifted physicist and mathematician,his first professorship came in 1805,followed by another at Paris in 1809. It was Ampere that proposed the right hand screw rule of the magnetic deflection around a current- carrying wire. He also showed in a classical experiment that two parallel wires carrying currents attract if the currents are in the same direction. In his theories of electrodynamics,he showed that the deflection of a compass needle by a nearby current was proportional to that current,a discovery that led to the unit of current being named after him | |
