Patent ID: 8860546

Claim:
A magnetic device, comprising: a first magnetic core comprising: a base having a first side, a second side opposite the first side, a third side that extends between the first and second sides, and a fourth side opposite the third side; a first contacting structure that protrudes from the base, the first contacting structure being positioned along the first and third sides such that outer surfaces of the first contacting structure form part of the first and third sides, the first contacting structure having a first inner surface that is opposite the first side and a second inner surface that is opposite the third side; and a second contacting structure that protrudes from the base, the second contacting structure being positioned along the first side such that an outer surface of the second contacting structure forms part of the first side, the second contacting structure being spaced from the first contacting structure such that a first inner surface of the second contacting structure faces the second inner surface of the first contacting structure, the second contacting structure also having a second inner surface that is opposite the first side and a third inner surface that is opposite the first inner surface of the second contacting structure; wherein a distance between the first inner surface of the first contacting structure and the first side is larger than a distance between the second inner surface of the second contacting structure and the first side.
