Abstract: An inductor, includes: a central post including a plurality of magnets, where each magnet includes an inductor and a primary magnetic core. The inductor at least partially surrounds the primary magnetic core and includes an auxiliary magnetic core and a winding. The winding 117 is embedded inside the auxiliary magnetic core and encircles the primary magnetic core 114. An upper jaw is connected to an upper end of the central post and a lower jaw is connected to a lower end of the central post 110. The upper jaw, lower jaw 130, and the primary magnetic core jointly form a magnetic path.
