Inductor

The utility model particularly provides an inductor. The inductor comprises a first magnetic core, a second magnetic core and an n-shaped end pole piece. The first end of the first magnetic core is provided with a first groove and a second groove which are parallel to each other; the first end of the second magnetic core is connected with the first end of the first magnetic core, and a first air gap and a second air gap are formed between the second magnetic core and the first magnetic core; the middle part of the end pole piece is arranged in the first groove and the second groove; and three end parts of the end pole piece respectively extend to the outer side of the second end of the first magnetic core. According to the inductor, the first air gap and the second air gap are arranged, so that the magnetic saturation resistance of the inductor is improved; the end pole piece is connected with the first magnetic core at the first groove and the second groove, so that the shaking of the end pole piece can be r
