 How does the distance from the axis center calculate as a leverage power when the distance to the magnetic force is varied?

Example:

A small electric motor calculates as a small distance from the axis center to the magnetic force used to turn the axis; while an exaggerated example of the same small motor could be a design that includes a 10 times longer distance from the axis center to the point at which the magnetic force is applied. A small motor is physically small in overall diameter perpendicular to the axis center line; while an electric motor designed to take advantage of greater leverage would be a 10 times larger diameter motor with the electromagnets housed further away from the axis center point.

How does that calculate out compared to the use of a friction causing gear reduction unit?
