Electrical Engineering/How much of a current would be produced


If I have a copper tube that is only 4mm diameter and about 1 inch long with a magnet inside (cylinder shaped and 3mm diameter) how much of a current could it produce when shaken. I know a copper tube wouldn't allow an individual circuit to be driven but I would imagine it would radiate some type of eddy current, just don't know in what range. Just trying to get a ball park idea. I would assume it would be in the low millivolt range.

This video on Lentz law may help.

THere are other such utubes that give some idea of the copper pipe phenomenon but as to your specific question I cannot give you an idea but, alas, for such a small tube and a magnetic of unknown field strength the current conduction and voltage produced would be in the micro area; in my opinion.

Hope this helps.
