Hi Rodolfo,

Simply turning off the current will make the 'door' magnet stick to
the end of the iron core. Which I think makes it and the EM a good
pair. If it was necessary to release the magnet with little or no force
(ie not manually) the current can be turned on to repel it. Still having
a think about that part of the mechanism
