Hello, I'm trying to glue a magnetic sheet on the back of a card but cannot find one thin enough and strong enough. The back of this card will never be seen. Ordered a few basic ones from Amazon but they aren't strong enough to do what I'm trying to do. To be clear, not trying to make a shim card with a metal sheet but actual magnetic sheet. This is to replace my deep clear by Paul Harris magnetic card that was destroyed (now discontinued). The new version Deep X uses a shim card so this doesn't work for me.

Any leads where to find something like this? Thank you.

You can use these thin magnets sandwiched between 2 cards....maybe that will work for you.

I'm not familiar with the effect but does the entire back of the card need to be magnetic to do it?

If you can't find a thin sheet, would two or three thin disks work as well? You could glue three of them centered on the back of a card.

If you need more strength, two more might fit on a standard playing card if you stagger them on the back.

I know you looked on Amazon but these are an inch across and 1/32" thick. That's less than 1 mm.

Just doing the brainstorming thing. The old, "What else might work?"

Oops! Missed seeing Dan's reply by five minutes! Same thin idea but better coverage!

I may have to go this route if I can't find the right kind of magnetic sheet. I have magnets of all sizes so I can certainly try.

Thanks for the tip Jerry. Just a note. 1/32 inch thick is .79 mm.
Neo magnets are brittle when they get to under 1mm. I would probably put several
neo magnets that aren't as wide to avoid cracking etc., as much as possible.

This link leads to "High Energy" flexible magnet material.

Their claim is that the magnet strength is higher than other flexible magnets of the same thickness (which, at .06" is probably too thick...).

It might be worth a try.
Cheers
