The method for collecting magnetic contaminants described in [*] uses a collector formed by encapsulating a SMCO5 magnet in an epoxy and bonding the encapsulated magnet to the end of a non-magnetic rod. In the improved magnetic sampler, the SMCO5 magnet 1 (Fig. 1) is encapsulated in a premolded plastic holder 2 using epoxy 7. Holder 2 has three equally spaced standoffs 3 (Figs. 1 and 2) to keep the magnet 1 at a fixed distance from the surface 6 being sampled. An index mark 4 aids in determining the starting point during subsequent analysis of the collected particles. Also, a gold coating is sputtered onto the entire exterior surface 5 because the analytical equipment requires a conductive surface.
