A motor torque ledger starts with a checked magnetic force, then multiplies by the lever arm to see whether that force can turn a rotor. The 24 N force and 1 m arm give exact torque only for the declared field-current-length source and ideal right-angle geometry; real machines include fringe fields, nonuniform flux density, winding resistance, saturation, heating, alignment error, friction, and force/torque measurement uncertainty.
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.
