rare earth magnets are not made in large sizes for some reason
Actually, I've found a wide array of sizes available from the following provider:

I got some that are 1" long by 1/2" wide and about 1/4" thick...whoa! I can barely pull them apart! A few of those would probably retain the wing on an ultralight!!
I also found that Lee Valley Tool & Supply is a good source for smaller sizes. Good prices too, especially when purchased in bulk.
