Does diamagnetism cause a faster orbital spin

[Faraday123]

Due to diamagnetism in certain substances such as water, does this cause a faster orbital spin due to the change in magnetic dipole moment induced by an external magnet? I'm doing a Science-fair project at the moment and this is eluding me

Thank you

I think diamagnetism occurs more by rotating the orbit, rather than increasing orbital speed, which is quantized and stays constant.
