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.
highlighted = computed this step
One-meter arm keeps torque equal to force
Force 24 N applied at arm 1 m gives torque 24 N m.
τ=24×1=24
Two-meter arm doubles torque
Force 24 N applied at arm 2 m gives torque 48 N m.
τ=24×2=48
Three-meter arm triples torque
Force 24 N applied at arm 3 m gives torque 72 N m.
