When current passes through a conductor, it generates a magnetic field around the conductor in accordance with Maxwells Laws. As the intensity of this field tries to grow, the changing field induces an EMF in the conductor which is opposite in polarity to the that which caused the current flow (Lenzs' Law) and so the field limits it's own growth rate. This is called 'inductance' and is measured in Henries. The governing formula is V = L dI/dt where V is the applied voltage, L in the inductance, and dI/dt is the rate of change of the current (in Amps/second)

I don't think anybody knows. Other than its behavior.
