Abstract
A magnetic core includes a first core and a second core made of a material whose magnetic permeability is smaller than that of the first core and having an end. The end of the second core is in contact with the first core so that the first core and the second core cooperate to form a closed magnetic circuit. The area of contact between the end of the second core and the first core is larger than the area of the cross-section of the end as taken perpendicularly to the extending direction of the end of the second core.
