An inductor has a certain inductance, and it only blocks the change of current. If there is no current flowing through the inductor, it will try to block the current from flowing through it when the circuit is connected; if there is current flowing through the inductor, it will try to maintain the current unchanged when the circuit is disconnected. Inductors are also called chokes, reactors, and dynamic reactors.
