Faraday's Law states that the EMF around a closed loop is equal to which of the following quantities?
A : The flux of the magnetic field through a surface which has the loop as its boundary.
B : The negative of the time rate of change of the flux of the magnetic field through a surface which has the loop as its boundary.
C : The line integral of the magnetic field around the closed loop.
D : The flux of the electric field through a surface which has the loop as its boundary.
