How to use magnets correctly:

The maximum pull-out force of the fishing magnet described by us needs to be used on a flat and thick iron plate. When the magnet is fully absorbed on the iron plate, it will be difficult for you to directly and vertically disengage it. At this point, you need to move the magnet to the edge of the iron plate to make it separate.

If you use magnets on irregular, curved, too small and thin, non-ferrous metals, etc., the breakaway force will be very small or none.
