So this is what I know about inductors. I know that they "store" energy in their magnetic fields, they are resistant to change in current (dI/dt), they act like regular wires if the current becomes constant (so no magnetic field right?), and that the reason they oppose a change in the direction of the current is because a difference in voltage (an emf) caused by the change in the magnetic field which is due to a change in current as time passes? (Most important question) So I guess my question is, how exactly is there a change in current, would that only happen when we supply and cut off current from the circuit? Also if I use the one of the hand rules on a inductor and find the direction of the force, would that be the direction in which the inductor is opposing the current?
Diagrams that include the direction of the force in a circuit with an inductor and its magnetic fields would help.
