1. A magnetic induction device (MID) comprising:
- a magnetic core having a structure which defines a closed path for magnetic flux around a hollow portion;
at least one first winding formed by depositing at least two turns in their entirety on the magnetic core;
an insulation layer which coats the magnetic core and the at least one first winding and has a plurality of through-holes which are at least partially filled with a conductive material; and
at least one second winding formed by depositing at least two turns in their entirety on at least a portion of the insulation layer.
