I got new one from MB, $108 through my parts guy. Same rubber labeling as my old Bosch unit, which also ruptured years later. MB has 1 year warranty on item.
Mercedes calls it a magnet but that is technically incorrect, as I pointed out earlier. Just think, if it really is a magnet, it would stick to anything that is iron and stay in one position and not able to be moved into the open/ closed positions.

Wikis on electromagnets and solenoids:

Solenoid - Wikipedia, the free encyclopedia

An electromagnet is basically a coil of wire wound around an iron core (what you are incorrectly calling a magnet, the part that has to move, to do the actuation).

This monovalve assembly is an electromagnet, or solenoid:



Monovalve iron core actuator (what Mercedes calls a magnet? which it is not):
