this to me is simply a upside down version of George greens magnetic motor

or am I missing something?
Upside down the magnet sits on the magnetic field and spins,
rather than rotating below on the worktop
The principle is the same - just different method of acheiving same outcome.
Credit to Flying Pyramid for alternate construction.
Credit to George Green!
No disrespect to anyone.
Have a great Day!
