Magnetic core
First Claim
1. A magnetic core made of metallic alloy having a linear or curved longitudinal axis, parallel to which a magnetic flux is to be guided essentially inside the magnetic core, the magnetic core being assembled from multiple rod-shaped or strip-shaped magnetic elements implemented parallel to one another, wherein at least one of the magnetic elements differs from the others in one or more of the following features:
- material permeability,curvature,length,shape and/or size of the cross-sectional area,presence, type, and position of notches in the magnetic elements, andwherein, viewed along a transverse direction extending through the thickness of the magnetic core and perpendicular to the longitudinal axis of the magnetic core, the magnetic elements have, with increasing distance from the center of thickness of the magnetic core outward towards a side of the magnetic core;
a decreasing material permeability and/ora decreasing length and/oran increasing curvature away from the longitudinal axis and/ora thickness which becomes smaller and/oran increasing number and/or growing depth of notches.

Abstract
A magnetic core (1, 1′, 20, 28, 29, 58, 61, 70, 70′, 80, 80′, 90) for a magnetic component has a longitudinal axis parallel to which a magnetic current is to be substantially guided inside the magnetic core. The magnetic core consists of a plurality of magnetic elements (2, 3, 4, 5, 6, 7, 8, 29, 30, 35, 36, 38, 39, 40, 48, 49, 52, 53) shaped like bars or strips arranged parallel to one another, at least one of the magnetic elements (2, 3, 4, 5, 6, 7, 8, 29, 30, 35, 36, 38, 39, 40, 48, 49, 52, 53) is different from the other magnetic elements in one or several of the following characteristics: permeability of material, curvature, length, shape and/or size of surface area, presence, type and location of notches in the magnetic elements.
