Query: Induced currents, frozen charges and the quantum Hall effect breakdown   Puzzling results obtained from torque magnetometry in the quantum Hall effect
(QHE) regime are presented, and a theory is proposed for their explanation.
Magnetic moment saturation, which is usually attributed to the QHE breakdown,
is shown to be related to the charge redistribution across the sample.
