Question

Can flux pinning be used for propulsion in Earth's magnetic field?

Answer 1

I was wondering if the following steps would result in a net displacement on a spacecraft operating in Earth's magnetic field:

Turn on a superconductor

Use a linear actuator to shift some mass

Turn off the superconductor

Shift the mass back to its original position

Repeat
