Is it possible? I've been looking at detachers but they're too expensive and I was thinking why wouldn't a countersunk neodymium magnet be able to open up magnetic hard tags? Let me show you what I mean, magnets like these:
They have the same shape as the commercial detachers and can be just as strong, and will be lighter and more portable.
I've tried it before but with a rectangular magnet and it didn't work so I think the dimensions and thickness have to be a certain size.
Has anyone had any luck with this sort of stuff?
Oh and before anyone says post in the shoplifting tips and techniques thread, this isn't a tip or technique, I'm asking a question.
