As can be seen from the yields of the above examples and comparative examples, the yield of the magnetic component using the covering body 11 can reach 99%, while the yield of the magnetic component not using the covering body 11 is very low because: once one of the permanent magnets is damaged, the entire magnetic assembly is discarded.
The same or similar reference numerals in the drawings of the present embodiment correspond to the same or similar components; in the description of the present application, it should be understood that if there is an orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", etc. based on the orientation or positional relationship shown in the drawings, it is only for convenience of description and simplification of description, but it is not an indication or suggestion that the indicated device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes, and are not to be construed as limitations of the present patent, and those skilled in the art can understand the specific meaning of the above terms according to their specific circumstances.
The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
