Can Earth's Magnetism Be Harnessed for Aircraft Lift?

AI Thread Summary
The discussion explores the potential of harnessing Earth's magnetism for aircraft lift, focusing on magnetic lift and electromagnetism in engines. The author, a meteorologist and pilot, expresses interest in innovative aviation design but acknowledges limited knowledge of magnetism and the Earth's magnetosphere. It is noted that the Earth's magnetic flux density, ranging from 25 to 65 microtesla, is too weak to significantly contribute to aircraft lift. Participants agree that the magnetic field is insufficient for practical applications in aviation. Ultimately, the concept appears unfeasible due to the weak nature of Earth's magnetism.

Hello,
I have an idea i have been working on for some time. I am a meteorologist and pilot, and i love aviation, especially design. I have been playing with the idea of magnetic lift (as in when one magnet is repelled from another magnet) or electromagnetism in an engine, to create a different form of lift for an aircraft, and a more efficient engine. But what i have been thinking about recently is the magnetosphere and the magnetism of the earth. Unfortunately i know very little about both subjects. My question then, is can the magnetism in or around the Earth be used to create any sort of lift? or has it been tried before?

I won't bother with it. It is much too weak to matter for an aircraft lift.
 
The Earth's magnetic flux density ranges from 25 to 65 microtesla.
So as nasu said, it's a very weak field.

Thread 'Why measure the speed of light in one direction?'

It may be shown from the equations of electromagnetism, by James Clerk Maxwell in the 1860’s, that the speed of light in the vacuum of free space is related to electric permittivity (ϵ) and magnetic permeability (μ) by the equation: c=1/√( μ ϵ ) . This value is a constant for the vacuum of free space and is independent of the motion of the observer. It was this fact, in part, that led Albert Einstein to Special Relativity.

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
