The N pole and the S pole of each magnet are connected to the S pole of the adjacent magnet. The adhesive layer is adhered between the magnets and the main body. When the magnetic member is in an extended position relative to the magnetic conductive member, the magnets generate a magnetic attraction force to magnetically attract the magnetic conductive member so that the magnetic conductive member The first magnetic conductive end moves toward the first connecting end along the axial direction and resets.

A second object of the present invention is to provide a method for manufacturing the magnetic component.

Therefore, the manufacturing method of the magnetic component of the present invention includes the following steps:

(A) Prepare a main body extending along an axis and a plurality of unsaturated magnets.
