A magnetic torque ledger cites a checked force source. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

Magnetic torque cites a checked force source
The force source is 24 newtons, and the lever arm is 1 meter.
τ=1×24=24Nm
No continuous motor curve is claimed
This finite training ledger shows torque 24 newton meters from one checked force.
