Is a speaker a solenoid?
Not all electromagnets are solenoids. I looked at a few definitions of "solenoid" just now, and the common feature was that they all either moved an armature inside the coil, or moved a coil between permanent magnets. From what I can see, neither the bell nor the magnetic clutch fits that category.
What matters in the end is not what I think "solenoid" means, or what you think it means, but what the GDC thinks it means. Until someone asks and gets a clear answer, I'm personally going to be conservative and eschew electromagnets in general unless they satisfy the motor or electric solenoid actuator rules.
