Fiber Optic current measurement.

[Chuck Britton <britton@ODIE.NCSSM.EDU>]

Can anybody supply an order of magnitude estimate of the amount of
rotation to be expected around a few amps of current? (i.e. should I
even TRY detecting it with some simple polaroid filters or are we
talking about some rather sophisticated detection system?)

I've got some surplus fiber that is just BEGGING to be used.
