Description

The object of the experiment P3.3.3.4 is the former electrodynamic definition of the ampere. Here, the current is defined on the basis of the force exerted between two parallel conductors of infinite length which carry an identical current. When r represents the distance between the two conductors, the force per unit of length of the conductor is:

This experiment uses two conductors approx. 30 cm long, placed just a few millimeters apart. The forces F are measured as a function of the different current levels I and distances r.
