Geologist Pendulum Pencil Magnet is ideal for swing testing for magnetic media. Designed in the shape of a pencil with pocket clip and Neodymium Magnet tip.
A Stainless Steel spring wire clip is located at the middle. When the magnet is held, or a line attached to the pivot clip, the “pencil” pivots on this center holder.
When passed over a Core Sample the Neodymium Magnet at the tip is attracted to magnetic minerals present in a rock specimen brought into its proximity.
