Hmm that's weird, I've had the same thing happen and they got stuck bare magnet to magnet on the back but the fan part was still attached and they came apart no problem. Did you get them stuck together with just the magnets? If so you probably do not want to use anything sharp or the magent will attach to ie. Screwdriver bad idea. Once the coating on the magnet is damaged you will run into rust problems shortly down the road, worst comes to worse you can purchase new parts from the Eco Tech parts store.
