[0002] An inductor is an element capable of converting electric energy into magnetic energy for storage. The structure of an inductor is similar to that of a transformer, but it has only one winding. An inductor has a certain inductance, and it only impedes the change of current. The earliest inductor was an iron core coil used by British scientist Michael Faraday to discover the phenomenon of electromagnetic induction in 1831. In 1832, Joseph Henry, an American scientist, published a paper on the phenomenon of self-induction. Therefore, the unit of inductance is named after him, abbreviated as henry. In the mid-19th century, inductors were practically applied in devices such as telegraphs and telephones.

[0022] Example 2: Please refer to Figures 1-5 Compared to Embodiment 1, this utility model provides an air gap avoidance inductor, which further includes: a core material assembly 4, an upper limiting ring 41 with its middle part slidably connected to a lower plug-in seat 21 via a central air gap rod 25, a lower end of the upper limiting ring 41 fixedly connected to a low permeability magnetic separator 44, an upper end of the lower limiting ring 42 also fixedly connected to the low permeability magnetic separator 44, a middle part of the lower limiting ring 42 with its middle part slidably connected to the lower plug-in seat 21 via a central air gap rod 25, a middle part of the iron core disc 43 with its middle part slidably connected to the lower plug-in seat 21 via a central air gap rod 25, and a low permeability magnetic separator 44 fixedly connected to the upper and lower ends of the iron core disc 43. The low permeability magnetic separator 44 allows air gaps to be generated between multiple iron core discs 43, significantly increasing the total magnetic reluctance of the magnetic circuit and limiting the peak magnetic flux density. A through slot 45 is provided in the middle of the upper limiting ring 41 and the iron core disc 43, and a coil 46 is wound around the outer wall of the iron core disc 43.

[0023] In this embodiment: When it is necessary to install and fix the coil 46 and its upper device, the lower pin can be pulled through the lower plug 21 when the coil 46 is wound on the iron core disc 43, and then the pin slot 13 embedded in the pin part 12 can be pulled to facilitate assembly and connection with external devices. The low permeability magnetic separator 44 can create air gaps between multiple iron core discs 43, which significantly increases the total magnetic resistance of the magnetic circuit and limits the peak magnetic flux density. The effective permeability of the magnetic core is reduced because the hollow slot 26 on the central air gap rod 25 is connected to the empty slot between the iron core disc 43.
