Specifically, the magnetic conducting member 30 is made of a high magnetic conducting material, which may be a high magnetic conducting soft magnet, and has a high magnetic permeability, and can perform a better function of collecting magnetic induction lines, when the magnetic conducting member 30 exists around the suspension base 10, the magnetic induction lines of the magnetic field are preferentially conducted from a position with a low magnetic resistance, that is, conducted through the magnetic conducting member 30 of the present invention, so that the magnetic conducting member 30 can partially or completely short-circuit the magnetic induction lines in the magnetic field, and therefore, the magnetic conducting member 30 can change the distribution of the magnetic induction lines of the magnetic field to change the magnetic flux density of the magnetic field, thereby changing the magnetic induction intensity of the magnetic field. Understandably, magnetic conduction member 30 is the U type, magnetic conduction member 30 is equipped with first face 31, second face 32 and third face 33, and wherein first face 31 and second face 32 are connected to third face 33, and when first face, second face and third face were not in the permanent magnet and/or the electro-magnet that supply magnetic assembly simultaneously around, the short circuit effect did not reach, consequently, magnetic conduction member 30 can set up to: the first surface and the third surface are fixedly and immovably arranged near the S pole or the N pole of the permanent magnet and/or the electromagnet of the magnetic assembly, and the second surface is short-circuited after being close to the permanent magnet and/or the electromagnet of the magnetic assembly in a translation and rotation mode.

Similarly, the magnetic supply assembly 12 may be a ring-like magnet composed of a single permanent magnet and/or electromagnet, or may be a ring-like magnet composed of a plurality of permanent magnets and/or electromagnets.
