I studied a little bit this gyroscope matter. Actually for space applications permanent magnets are used for gyroscopes. Now depending on the strenght of the magnetic field created by a permanent magnet you could also get an amplification of the output current. Where is the loss? In the fact that after some years the permanent magnet will lose its magnetization. But in the case of space applications (and I think also of the C1) the magnet keeps magnetized for many years.
