If magnetic flux throgh a closed surface always remains 0, then how does the magnetic flux change ? In electomagnetic induction we study that change in magnetic flux produces induced emf? But how is it possible ? Does the concept of electromagnetic induction is in accordance with Gauss's law of magnetism?

EMF is induced when the number of magnetic lines of force linked with a surface changes. The net flux through a closed surface always remains zero because flux coming in is equal to the flux going out. This is true for a magnet that is static. Now if the magnet is moved inside the closed surface then obviously the magnetic field intensity or the flux will change w.r.t. a given point with time. Still total magnetic flux associated with the closed surface will be zero.
