I deconstructed a stepper motor. Would this be considered a 4 pole motor?

 

Not really. It's a bipolar 2-phase motor. Apparently the Howard 1-19-4203 has 100 step/rev.

I thought they were called bipolar because current can flow in two directions for a given coil. I was asking, in terms of general motor terminology, how many magnetic poles does this motor have?

 

manufacturers of these types of synchronous motors typically specify the number of teeth, and you'll find one less on the stator compared to rotor, so is it the stator or rotor number that's specified, I have no clue. Slo-syn popularized this motor style years ago.
