Clarification please?

If the electromagnet in the lock moves something to release the latch it is illegal as an electromagnet providing motion has been ruled by the GDC to be a solenoid per the responses Eric linked.

If the electromagnet just holds the part in place, then releases it, with no motion of latch parts then you should be OK.
