Abstract
The dynamical behavior of a simple rotating mechanical system that carries a charge on its surface and is accelerated by a falling mass is considered. It is shown that a fraction of the total kinetic energy is missing and that exactly this fraction of energy has been stored in the magnetic field distribution. The conservation of electromagnetic angular momentum is also discussed on the same basis. The concept of an electromagnetic moment of inertia is introduced to establish a close parallel with the concept of mechanical moment of inertia in classical dynamics. It is suggested that the present mechanical system can be used as a teaching tool at the early-to-intermediate level of an undergraduate physics program to ease the transition from the dynamics of rigid bodies to that of more abstract fields.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
