Magnetic device

A magnetic device, comprising:

• a body, comprising a top surface and a bottom surface;
• a first conductive wire, wherein the first conductive wire comprises a first terminal part, a second terminal part, and at least one first winding turn to form a first coil, wherein the at least one first winding turn of the first coil is disposed in the body;
• a second conductive wire, wherein the second conductive wire comprises a third terminal part, a fourth terminal part, and at least one second winding turn to form a second coil, wherein the at least one second winding turn of the second coil is disposed in the body, wherein a straight line passes through a first hollow space of the first coil and a second hollow space of the second coil;
• and
• a first electrode, a second electrode, a third electrode, and a fourth electrode, wherein the first terminal part is electrically connected to the first electrode, the second terminal part is electrically connected to the second electrode, the third terminal part is electrically connected to the third electrode, and the fourth terminal part is electrically connected to the fourth electrode, wherein a first straight-line segment passing through the first electrode and the third electrode does not cross over a second straight-line segment passing through the second electrode and the fourth electrode within the boundary of the bottom surface of the body, wherein the first coil is wound in a first direction when viewed from the first terminal part, and the second coil is wound in a second direction when viewed from the third terminal part, wherein the first direction and the second direction are opposite to each other.
