André-Marie Ampère Short Biography: André-Marie Ampere (born January 20, 1775 – died June 10, 1836 at the age of 61 years) is a physicist and the versatile French scientist who is also one of the pioneers in the dynamic electric field (electrodynamics). He was born in Polèmièux-au-Mont-d’Or near Lyon. Ampere is the first scientist to develop tools to observe that the two conductor rods placed side by side and both an electric discharge in the direction will attract each other and if the opposite direction will repel each other (electromagnetism).
In physics, the ampere is denoted by A, is the SI unit of electric current. One ampere is an electric current that flows, such that in between two straight Conductor with infinite length, with a negligible cross section, and placed with a distance of one meter apart in vacuum, yielding a force of 2 × 10-7 newtons per meter.
This unit is taken from the name André-Marie Ampere, one of the discoverers of electromagnetism.
