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 suggestions for scoring and snapping magnets:
- Use a pointy knife or razor blade. A uninteresting blade will make it tougher to attain the magnet, which can lead to a jagged or uneven minimize.
- Rating the magnet shallowly. For those who 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 power may cause the magnet to interrupt in an uneven method.
