We derive electromagnetomotive force fields for charged particles moving in
a rotating Hall sample, satisfying a twofold U (1) gauge invariance princi
ple. It is then argued that the phase coherence property of quantization of
the line integral of total collective particle momentum into multiples of
Planck's quantum of action is solely responsible for quantization in the Ha
ll state. As a consequence, the height of the all quantization steps should
remain invariant in a rapidly rotating Hall probe. Quantum all particle co
nductivities do not depend on charge and mass of the electron, and are quan
tized in units of the inverse of Planck's action quantum.
