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 ...

Why does earth's magnetic field change its direction?
I know that the earth's magnetic field is due to molten metal and ions flowing in its core. It has been found that the Earth's magnetic field changes its direction and it has even flipped once!
But, ...

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)? ...

Energy Budget: Is the Earth's magnetic field slowly decaying?
Earth's magnetic field is maintained by the dynamo effect, and I have no doubt that this effect could sustain Earth's magnetic field for a very long ("infinite") time.
It's my understanding that the ...

Do we need to know Earth's magnetic field locally?
I'm a high school student and in our course we have elements of earth's magnetic field (dip and other stuff) that lets us know the value and direction of magnetic field at any point on the planet.
I ...
