If the moon has a weak magnetic field could that be boosted by placing a copper anode/cathode at the poles powered by nuclear energy? Creating an excess of negatively charged particles at the north pole and positively charged particles at the south, creating a push/pull effect.
What about a powerful magnet over the northern pole to assist the existing magnetic field in capturing charged particles and boost the magnetic field strength.
What energies would this require? Is it feasible?
