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. This may create a stress focus that may trigger the magnet to snap aside cleanly on the scored line.
Extra Suggestions for Scoring and Snapping
Listed below are some further ideas for scoring and snapping magnets:
- Use a pointy knife or razor blade. A boring blade will make it harder to attain the magnet, which can lead to a jagged or uneven lower.
- Rating the magnet shallowly. If you happen to rating the magnet too deeply, it could be troublesome to snap it aside.
- Faucet the nail or punch alongside the scored line gently. An excessive amount of pressure could cause the magnet to interrupt in an uneven method.
