I'd be interested in knowing if anyone has tried these. I wonder if the magnetic fields on recording tape are strong enough to produce a display.

So I've been seeing this thing on Ebay, and I'm wondering if it might be a good substitute for the Arnold magnetic viewers we currently use to view tape tracks.
It's a magnetic viewing card made of green film.
