Patent Images
1. A magnetic element for wireless power transmission, which generates an induced electromotive force by magnetic coupling, wherein:
- in a cross section that matches the direction of magnetic coupling, a plurality of conductor sections through which alternating current flows in a single direction and a magnetic material section provided in at least one gap between the conductor sections are arranged in parallel in a direction perpendicular to the direction of magnetic coupling; and
each of the conductor sections or the at least one magnetic material section has one or more protruding regions which, or each of which, is a portion of conductor section protruding from the at least one magnetic material section in the direction of magnetic coupling, or a portion of the at least one magnetic material protruding from the conductor section in the direction of magnetic coupling.
