SUMMARY

The discussion centers on the feasibility of utilizing the Blandford-Znajek process to harness the rotational energy of charged black holes for accelerating unmanned probes during close flybys. The concept involves using the black hole's magnetic field lines as a 'magnetic assist' to enhance acceleration. Participants noted that the physics of this interaction may differ based on the mass of the object, suggesting that smaller particles would experience a greater influence than larger ones. Additionally, the potential application of this concept to other celestial bodies with high magnetic flux, such as neutron stars and magnetars, was explored.

With regards to the Blandford-Znajek process (about which I've only recently become aware), would be possible, at least in theory, to tap into the rotational energy of a charged black hole, this by using its revolving field-lines as a kind of 'magnetic assist' to increase the acceleration of, say, an unmanned probe making a close flyby? Or is this completely potty?

I would like to know if the physics behind this would vary with object mass. I think smaller particles would be greatly affected by this more than larger objects (Because black hole).
 
Moreover, it would be interesting to know if the above also applies to other celestial bodies with a high magnetic flux - neutron stars and magnetars especially.
