Review on Master Magnetics Magnet Fastener Diameter by Anthony Hales

These magnets are not as strong as advertised. I bought these hoping to mount one on one side of the 2mm plastic cover and glue the other to the other side. However, as the steel cup is molded against the magnet this is impractical as it has little to no holding power on one side and the polarity is the same for all magnets so the side where the force is acting will be repelled. other magnets. When he folds them like this, he can't hold anything thicker than a business card. I've also found that if you put these magnets close to other magnets they lose their magnetism. I put one on top of the neodymium magnet I had on my fridge and although I only connected them for a moment, the magnet became so weak it couldn't stick to the fridge through the layer of labels. My guess is that some of these reviewers received magnets that were subjected to strong magnetic fields at some point in the delivery and therefore won't even stick to the fridge. Either way, they really aren't very useful.
