An apparatus for measuring very high currents, and in particular direct currents, wherein a body of material exhibiting the Faraday effect, e.g., flintglass, is disposed in the magnetic field caused by the current flowing in a conductor. A polarized light beam is passed through this body of material and the displacement of the polarization plane of the light beam is measured as a measure of the current flowing in the conductor. Preferably the body of material exhibiting the Faraday effect forms a closed path around the current conductor which path is followed by the light beam.
