An inductor and a related apparatus are provided. The inductor includes an upper magnet yoke and a lower magnet yoke that are straight-shaped and are disposed in parallel. A first winding disposed on a first fiber post, and a second winding disposed on a second fiber post. The upper magnet yoke, a first upper fiber post, and a second upper fiber post are integrally molded. The lower magnet yoke, a first lower fiber post, and a second lower fiber post are integrally molded. A clockwise/counterclockwise direction of a current in the first winding is consistent with a clockwise/counterclockwise direction of a current in the second winding.
