When I started to study magnetostatics it was said that magnetic fields are created by charges in motion, that is, they are created by currents. On the other hand, we have magnets and those have magnetic fields associated with them. In truth the magnetic field is such that the field lines connect the two poles. But on the case of magnets, there is no current.
So how is the magnetic field of magnets created if not by currents? How dos it relate to the magnetic field created by currents and given by Biot-Savart law?
