Is Earth's magnetic moment vector oriented parallel or antiparallel to the sun's magnetic moment?
Just curious how these two magnets are spatially related to?
And in case there is no any special preferred particular orientation, what is anyway their spatial orientation relation (relative angles)? ...

Is it possible to use forces on a current carrying conductor due to Earth's Magnetic field to levitate?
When current is applied, a conductor within a magnetic field feel a force. This is the Lorentz Force. I was thinking if it is then possible to apply as much current on a conductor that it will start ...
