Thread: magnet questions

Im improving my refrigerator door magnets that get knocked off or shift around all the time. I dont want to deal with that again.

1. Will a piece of thick sheet metal on the backside of a thin but wide magnet provide most of the advantage of a cup?? Any good sources for thin cups? I'll probably use 3/4" or 1" wide neodymiums.

2. What thickness of neodymium magnet will saturate a refrigerator door?? I have a 1/32" magnet but with a layer of 5mil latex glove and the paint between them its significantly weaker than my larger neodymium magnets to the door.


3 What adhesive would be good for gluing latex rubber to a shiny magnet?? The friction from the rubber makes it much harder to slide around than a smooth magnet. I tried 3m 77 spray adhesive but it pulled off the magnet when sliding it around.

That's very good, learning, thank you for sharing
