Also, the use of the terms "a," "an," or "the" and similar referents do not denote a limitation of quantity, but rather denote the presence of at least one. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

Referring to fig. 1-2, there are shown an enameled wire and an electromagnet in the prior art, the center of the enameled wire is a conductor 20, which may be made of copper, aluminum, etc., and the exterior of the enameled wire is wrapped with an insulating layer 21. In the fabrication of an electromagnet (solenoid), in order to increase the magnetic field strength of the coil 2, it is usually provided on the outside to the housing 3 and the cover plate 4 as the magnetic conductive layer 22, so that there is enough magnetic field force to control the movement of the slide rod 5.

Referring to fig. 3, a magnetic conductive enameled wire is shown, and includes an electric conductor 20, an insulating layer 21, and a magnetic conductive layer 22, where the electric conductor 20 is located at a central portion of the wire body, the insulating layer 21 is wrapped around the electric conductor 20, the magnetic conductive layer 22 is wrapped around the insulating layer 21, a current is supplied to the center of the enameled wire, the insulating layer 21 ensures safety of energization, and the magnetic conductive layer 22 on the surface provides a magnetic conductive effect, and when an electromagnet is assembled, it is not necessary to mount the housing 3 and the cover plate 4 on the periphery of the framework 1, so that the structure and the manufacturing process of the electromagnet are simplified, the cost is.

Referring to fig. 4, an electromagnet is shown, which includes a framework 1 and a coil 2 disposed on the framework 1, where the coil 2 is formed by winding the aforementioned magnetic conductive enameled wire, and when winding, the enameled wire is wound around the framework 1 in a circle and layer by layer, and adjacent portions of each circle of layer in the coil 2 are tightly attached to each other, so that the magnetic conductive layers 22 of the enameled wire in each circle of layer are in direct contact with each other to form a complete magnetic conductive structure, and an axial magnetic field can be generated during operation, and is just matched with the axial movement of the slide rod 5. If the magnetic conduction layer 22 is arranged inside and the insulating layer 21 is arranged outside, direct contact is not generated between the magnetic conduction layers 22, and the formed magnetic field cannot be matched with the moving direction of the slide rod 5 due to the influence of the surrounding arrangement of the enameled wire.

After the enameled wire is wound on the framework 1, although the magnetic conduction layer 22 on the surface is contacted to form an integral magnetic conduction structure, the enameled wire is generally round, and is in tangential contact with each other, so that a plurality of gaps are reserved, and the gaps can be filled with magnetizers to strengthen the whole magnetic conduction structure.
