Three lever-arm rows show the same checked magnetic force producing larger torque farther from the pivot.

The same magnetic force makes larger torque at larger lever arm. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

One-meter arm keeps torque equal to force

Force 24 N applied at arm 1 m gives torque 24 N m.

Two-meter arm doubles torque

Force 24 N applied at arm 2 m gives torque 48 N m.

Three-meter arm triples torque

Force 24 N applied at arm 3 m gives torque 72 N m.
