Abstract

An inductance coil having a core in the form of a closed loop, particularly of circular cylindrical shape, said core comprising a plurality of mutually superimposed layers of a continuous strip (1, 1', 11) of magnetic material. To obtain air-gap properties with respect to the core said core is provided with perforations or slots (3, 3', 13) extending radially through the core, said perforations or slots in each layer being limited axially by at least one unbroken part (4, 4') Which holds the layer together. Preferably the unbroken parts (4, 4') in each layer have an area such that said parts become saturated at the operation conditions under which the inductance coil is intended to work, whereas said parts also obtain air-gap properties.
