From first principles and trying to make it really simple. In an inductive circuit, the difference in potential causes a current to flow. As the current flows it induces a magnetic field. If this magnetic field in interacting with other magnetic fields (Itself or another) the other magnetic field suppresses the buildup of the magnetic field that this current is trying to establish. This inhibits the current rise as the voltage increases. In a DC circuit this happens at switch on and to a less ...
