An inductor includes a coil and a core. The core covers the coil and includes a plurality of magnetic particles. Each of the magnetic particles includes a nucleus and a first shell enveloping the nucleus. The nucleus and the first shell are formed by different materials with different specific gravities. When the nucleus includes a polymer material, the first shell includes the first magnetic material. When the nucleus includes the first magnetic material, the first shell includes the polymer material. |
