It's actually a narrow interpretation. A COTS electromagnet is clearly permitted as long as it is not actuating something. A COTS electro-magnetic actuator is not permitted under any circumstances.

Make sure you have a printout of that Q&A on hand at all times

I just hope you don't get a finicky EE as an inspector.
There could be some big arguments there......
The only thing that is not clear is whether a COTS electromagnet is permitted if it is actuating (forcibly moving) something external to itself on the robot. That specific question has not been explicitly addressed by GDC by either of the Q&A responses, since both questions were asking about an electromagnet simply holding something, not moving something.

There have been no arguments about electromagnets used as a holding device, that I am aware of. I don't expect any. The GDC ruling was quite unambiguous.
