The dynamic electromotive force of the first surface integral is generated by the closed coil moving in a non-uniform magnetic field in space. In a uniform magnetic field, the electromotive force is zero.
The dynamic electric potential of the first surface integral is produced by the movement of the closed coil in a non-uniform magnetic field in space, in which the electric potential is zero.
