The circulation of a vector field is the closed line integral of the dot product between the vector and the infinitesimal displacement vectors along the curve. Therefore, the sign of circulation depends on which way around the curve you take the integral.
This is all very well, but this equation (attachment) establishes that the circulation of the electric field is positive when the magnetic flux is decreasing, and it is negative when the flux is increasing. But how do I know which way should I take the circulation (clockwise or anticlockwise)?
