Description

In the experiment P3.3.4.4, the magnetic field of a long, straight conductor is measured for various currents I as a function of the distance r from the conductor. The result is a quantitative confirmation of the relationship

In addition, the magnetic fields of circular coils with different radii R are measured as a function of the distance x from the axis through the center of the coil. The measured values are compared with the values which are calculated using the equation

Using a sensitive magnetic field sensor, the experiment is performed at low current levels.
