Reverse Direction From Produced Of energy Quantity Who Them Internal Angle With Multiply If you do That The value Found Will go Him Torque Says . That is Energy * Conic Distance Of the book In language , when Conductive Inside With Flowing Current Force Generated Will And Conductive Clock Wise In turn Try Will Then This Friction The trend Torque Says. Of torque The value Tell me And Of rotation Center From Perpendicular Distance Of Of product Equal. T = F * r T = Torque, F = Force r = Rotation Center To be Perpendicular Distance. Of torque Because Basically The opposite Voltage Creation Become Stays.
