The electromagnets had some "oomph" I seem to remember the engineering
beacon moving in frequency slightly when they switched on ... I don't
remember if it was because of a sag on the DC bus, or the magnetic field
affecting the tuned circuits of the transmitter.
But you bring up important points, if we are to do orbit adjustments,
we need to do attitude determination and control in addition to getting
a motor aboard. No easy feat in a 3U cubesat!
