Abstract: Two ferromagnetic elements are disclosed that delimit a region for an electrical conductor, in which a current intensity should be measured. Each ferromagnetic element has an end surface. The end surfaces of the two ferromagnetic elements face each other and delimit an air gap. A magnetic field sensor is arranged in the air gap or near the air gap. The region delimited by the ferromagnetic elements is open on a side opposite the air gap and can thus receive the electrical conductor. The current intensity is measured by means of a magnetic field measurement. The ferromagnetic elements can be, in particular, L-shaped.
