Scoring and snapping is a straightforward and efficient methodology for slicing magnets. It includes making a weak spot on the magnet’s floor that permits it to be simply damaged.
To attain the magnet, use a pointy knife or razor blade to make a shallow lower alongside the specified lower line. Watch out to not lower via the magnet utterly.
Subsequent, place the magnet on a tough, flat floor and align the scored line with the sting of the floor. Utilizing a pointed object, similar to a nail or punch, gently faucet on the magnet alongside the scored line. It will create a stress focus that may trigger the magnet to snap aside cleanly on the scored line.
Further Suggestions for Scoring and Snapping
Listed here are some extra ideas for scoring and snapping magnets:
- Use a pointy knife or razor blade. A uninteresting blade will make it harder to attain the magnet, which can lead to a jagged or uneven lower.
- Rating the magnet shallowly. Should you rating the magnet too deeply, it might be tough to snap it aside.
- Faucet the nail or punch alongside the scored line gently. An excessive amount of drive may cause the magnet to interrupt in an uneven method.
