I know that solid gold wouldn't rust or anything like that, but since the magnets are plated, wouldn't the gold come off? Kind of like a cheap gold ring. Since it's not solid gold, the gold eventually rubs off on someones finger. TH160

I would use nickle or chrome or something like that, its cheaper. if you want something durable though, just coat it with a plastic. it wont rust, its UV tolorant, and resistant to alot of chemicals

So does gold last shorter or long than nickel or chrome? The extra price for the gold is all right, it's not that much. I am about to buy a large ceramic magnet, 6 3/4" x 4", from Magnetic Arts (http://www.magneticarts.net) it is magnetized
parallel to thickness. I was looking at the chart on their site, and wanted to make sure I understood it properly. Parallel to thickness means that one 6x4" surface is north and the other 6x4" surface is south, right? Thanks all!

what do you plan to use these for? finding a coating that matches the use is the best way to go about this. getting It chromed or galvanized or plastic coated will be much more durable than using thin gold foil. those coatings will be just as resistant to most situations as gold.

Sorry for the delay. The one use is in a weather device that will be used outside, in possibly snow, rain, extreme heat, and cold. The other is medical related, and possibly in constant contact with skin. It's not going to be taped to your forehead, like I said earlier, that was just an example. Thanks!

If it's going to be contacting the skin then use gold; it won't react to human sweat and body oils.
As for the weather station, pretty much whatever should work as long as the magnet doesn't get drenched in salt water constantly.
