摘要：
A spacer contains a magnetic filler and is disposed between the magnetic conductive balls. The magnetic filler produces an indirect magnetic attractive force on the balls, therefore, when the interval between the two neighboring balls is overlarge, the spacer will not tip over under the effect of gravity or centrifugal force, but will be adsorbed on the balls by the magnetic filler.
