I wonder if it's possible to use a 2nd electromagnet to weaken the field at the point where it holds the door? Alternately, could the discharge from a high capacity capacitor damage the coil somehow?
Or, perhaps an AC source with another coil outside the door to interfere with the DC current around the core on the electromagnet? I'm not going to think too deeply about this because, well, because Rubycon has already thought about this & has the answer.
