An apparatus for providing vehicles with energy by magnetic induction, wherein the apparatus comprises:
- a primary side electric conductor configured to generate an electromagnetic field while an alternating electric current flows through the conductor;
- and
- a field shaping layer comprising magnetizable material configured to shape magnetic field lines of the electromagnetic field, wherein:
- the field shaping layer comprises a plurality of elements made of the magnetizable material fixed to a continuous supporting layer made of electrically conducting material that is non-magnetic;
- the plurality of the elements made of the magnetizable material is arranged in rows and columns with a gap in between each pair of neighbouring elements in the rows and in the columns;
- the neighbouring elements are positioned at a distance to each other;
- the primary side electric conductor is positioned at a distance to the plurality of elements;
- and
- the field shaping layer is folded or coiled with respect to one of two possible directions of the rows and columns of the magnetizable material.
