Magnetic element and image output device comprising same

A magnetic element comprising:

• a first core;
• a second core disposed on the first core;
• a bobbin comprising a through-hole formed in a center portion thereof, the bobbin being at least partially disposed between the first core and the second core;
• and
• a first coil unit and a second coil unit at least partially disposed on the bobbin,
• wherein at least one of the first coil unit or the second coil unit comprises a plurality of conductive wires disposed around the through-hole, each of the plurality of conductive wires comprising a first end portion and a second end portion,
• wherein the bobbin comprises:
• a first portion formed to allow the first end portion and the second end portion of each of the plurality of conductive wires to be disposed thereon;
• and
• a second portion formed opposite the first portion in a horizontal direction, with the through-hole interposed therebetween,
• wherein portions of the plurality of conductive wires overlap each other vertically on the second portion,
• wherein the plurality of conductive wires includes a first conductive wire, a second conductive wire, a third conductive wire, and a fourth conductive wire disposed around the through-hole, each of the first to fourth conductive wires including the first end portion and the second end portion, and
• wherein the first end portion of the third conductive wire, the first end portion of the first conductive wire, the first end portion of the fourth conductive wire, the first end portion of the second conductive wire, the second end portion of the first conductive wire, the second end portion of the third conductive wire, the second end portion of the second conductive wire, and the second end portion of the fourth conductive wire are disposed parallel to each other on the first portion.
