FIELD: electricity.
SUBSTANCE: flat inductance coil with increased magnification factor, near which a layer of magnetic material is arranged, is characterised by the fact that the magnetic material layer, the value of relative tangent of magnetic losses of which is <10-4, is located tightly to external and/or internal boundaries; with that, sizes of the above layer of magnetic material are in the following ranges: height h of the magnetic material layer is at least by two times bigger than thickness d of the coil, and width w of the magnetic material layer is 5-10% of inner radius b of the coil.
EFFECT: increasing a magnification factor without any increase in density of magnetic flux or inductance.
