I have a question about direction of vectoral line integral in formula of electric potential and electric field. In electrostatic I assumed \$B\$ is positive potential and \$A\$ is negative potential so the boundary of the integral is negative to positive and also there is a minus sign outside the integral, and also \$d\ell\$ direction […]

- Tags and also \$d\ell\$ direction is always positive. This approach was always true in my electromagnetic 1 class. For example if electric field i, I have a question about direction of vectoral line integral in formula of electric potential and electric field. In electrostatic I assumed, time varying magnetic fields create emf. But this time the line integral is closed loop and I am very confused, what should I choose? Which direction is positive and negative and where is the minus sign of the integral? For example if path is a circular
