Timepiece movement comprising a rotating element provided with a magnetized structure having a periodic configuration

A timepiece movement comprising:

• a mechanism including:
• a rotating element, provided with an annular magnetized structure exhibiting an angular variation of at least one physical parameter defining said annular magnetized structure, and
• a first set of magnetic elements which is formed of one functional magnetic element or of a plurality of functional magnetic elements, said first set of magnetic elements not being integral in rotation with said rotating element and having overall with the annular magnetized structure a first magnetic interaction which generates on said rotating element a first magnetic disturbance torque;
• and
• a second set of magnetic elements which includes a magnetic compensation element or of a plurality of magnetic compensation elements, said second set of magnetic elements not being integral in rotation with said rotating element and having overall with the annular magnetized structure a second magnetic interaction which generates on said rotating element a second magnetic disturbance torque, and
• wherein the second set of magnetic elements is arranged relative to the first set of magnetic elements such that the maximum absolute torque value resulting from the addition of the first and second magnetic disturbance torques is lower than the maximum absolute value of the first magnetic disturbance torque.
