I’ve been wanting to make some fridge magnets of my cats, for the cat shelter to sell along with my cards. Turns out they cut just fine in the GF. The magnet sheet I used was this stuff.
My cutting conditions were: 2 passes of Speed 250, Power 100, focus height 0.026".
The second pass gives you lots of fun sparks!
Here’s the interesting part: I was afraid that the heat would demagnetize this fairly weak material. Turns out that doesn’t seem to be the case. But I did a little research anyway and found this cool article: http://www.kjmagnetics.com/blog.asp?p=remagnetize-flexible on how to remagnetize flexible fridge magnets. You have to place neodymium ring disc magnets on a bolt so they repel each other, tighten the bolt, and swipe the assembly across the sheet magnet, which realigns the magnetic field (or something). I went ahead and ordered some of the magnets, although I now need to get to the hardware store to get a bolt that will go through the discs. I also ordered the coolest thing of all: a small sheet of magnetic field viewing film. It works great! Here’s a view of the cut magnets as viewed through the film:
And here’s what the sheet magnet looks like before cutting:
I took one of the magnets I had cut and deliberately messed up the magnetic field by rubbing a strong neodymium magnet over it. You can really see the difference:
I’m hoping that once I get a bolt that fits, I’ll be able to restore that piece to its original condition.
Anyway, just thought this might be of interest!
