Quote from: RE on Dec 02, 2023, 07:18 PMDid you take that photo recently? When did you go by there? If so, I would say the neodymium magnets are oxidizing faster than I expected. I thought the epoxy coating would keep the air out better. I wonder if they still hold their magnetic properties? Did you try sticking any ferromagnetic object to them?
Photo from early November. Didn't realize they were magnets, looked like support pins or some part of holding it together. The locations on the US map look like they are doing the same thing. Are they magnets?
