Subject: Position of magnetic damper relative to pivot

I understand one wants the magnetic damping MD effect to be about a 10th
reduction in intensity for consecutive cycles of the boom.
It seems you can have a strong MD close to the pivot or a weak MD near
the coil end to achieve this damping effect.
With a fixed strength MD one can tune the intensity reduction by
shifting the position of the MD along the boom.
Are there other good reasons for the position of the MD.
