Abstract
Apparatus for conveying magnetically attractable particles from a first position to a second position including a support member, such as a disc, adapted for rotation and having at least one surface area at which a magnetic field is presented that passes between the first and second positions. More than one support member, each having at least one surface area at which a magnetic field is presented provides another arrangement wherein the support members are serially arranged to extend between the first and second positions so the magnetically attractable particles are carried from one support member to the next.
