Attach the other electrode to the permanent magnet, using the same methods used to attach to the crystal. Attach the two remaining wire ends to the voltmeter's electrodes (polarity is not important). Set the voltmeter for a low power setting (~1v). Strike the crystal with the magnet, but not hard enough to cause damage.

Sand casting: This is used to produce small lots of custom metal parts with complex geometry. There is no tooling - sand is used as the tooling material and a sand mold is formed around a positive model of the part (typically a CNC version of the metal part). The positive is removed, the two halves of the sand mold is put together and …

Sand casting, the most widely used casting process, utilizes expendable sand molds to form complex metal parts that can be made of nearly any alloy. Because the sand mold must be destroyed in order to remove the part, called the casting, sand casting typically has a low production rate. The sand casting process involves the use of a furnace ...

Lapping is the removal of material to produce a smooth, flat, unpolished surface. Lapping processes are used to produce dimensionally accurate specimens to high tolerances (generally less than 2.5 µm uniformity). The lapping plate will rotate at a low speed (<80 rpm) and a mid-range abrasive particle (5-20µm) is typically used. Lapping
