Do not handle multiple magnets at the same time unless they are widely separated or stacked together. 6. When placing magnets together, place a spacing material between them such as a piece of plastic, wood or cardboard so that they are easy to separate when needed. 7. Maintain a distance of at least 3 feet from other magnets or magnetically susceptible items when handling the magnets. Pay particular attention to scissors, knives, screw drivers or any other metal objects. 8. To separate one magnet from the others, place them on a durable non-metal surface with the magnet-to-be-separated hanging off the table. Use one hand to firmly hold the other magnets on the table, especially those closest to the magnet being separated. Use the other hand to firmly hold the magnet you are separating. Push it down and away from the other magnets, until a magnetic attraction is no longer felt. Keep the separated magnets a safe distance from each other.
