The magnetically suspended brush assembly of the present invention includes a brush having a shaft and formed with a tail, and a ferule which secures an instrument tip, such as a brush tip. The ferule and shaft include a magnetic material, such as a steel bar or balls within the ferrule that can be magnetically attracted. Magnetic material may be placed during the making of the brush and put in the back end of the ferrule prior to attaching the handle either by crimping the ferrule to the handle or using an adhesive to do this. The tail end of the handle also incorporates the small addition of a similar magnetic material, preferably a magnetic stainless steel, and extends from the end of shaft, or the magnetic material may be embedded in shaft, or attached to the end, or painted or coated on the outside of the shaft. An instrument holder is also provided which in one embodiment has a single magnetic element to support a single brush. The brush is suspended tip-down and away from any surface so that the tip remains contaminate-free. The brush may be removed by grasping the brush and pulling away from the holder thereby breaking the magnetic attraction and removing the brush from the holder. |
