If an inductor requires a changing current to produce a voltage drop across itself Then is there any purpose to an inductor with constant current going through it? Is AC usually used with inductors since its always changing.
Inductors come in all shapes and sizes. They have various uses, many at the fundamental level basically exploit the inductor's mathematical function that ##v(t)\ =\ L.\dfrac{di(t)}{dt}##If an inductor requires a changing current to produce a voltage drop across itself Then is there any purpose to an inductor with constant current going through it?

That is a really poor way to learn things, just sitting there trying to visualize them in your mind. I suggest a textbook, or a course on video as much more effective ways to learn.I always found thinking of electromagnetism as oscillating charges as opposed to oscillating electromagnetic fields. Something more physical to grasp as an idea I suppose.
The way to appreciate inductance is working with it -I always found thinking of electromagnetism as oscillating charges
Think of magnetic flux as a massless fluid that surrounds any current.I always found thinking of electromagnetism as oscillating charges as opposed to oscillating electromagnetic fields. Something more physical to grasp as an idea I suppose.
