# (Myth or something innovative?) Idea for inductors/electromagnets

Hi, I wanted to share a little idea I had (which may have already been discussed), which would be: What if we take a pulsating DC current, modifying it into spiral loopies (Idk if this is possible), and applying this modified current to an Inductor, would that inductor´s efficiency be increased or would it become somewhat unstable?

- In short, a current that behaves like an inductor, applied to an inductor.

Efficiency to do what?
An inductor is just an inductor, it's neither efficient or inefficient by itself, it efficiency in a circuit depends upon what the inductor is designed to do.

Hm, i could have included that. One of those efficiencies would be in the case of electromagnetism, buffing the force of attraction metric.

The sentence is already self-explanatory... Btw, I had recently started to study about inductors and this "idea" was actually just a curiosity of mine. If you could explain to me why this is weird or somehow impossible, i would appreciate it.

There is no standard meaning to “sprial loopies” so there the sentence explains nothing.

Wild speculation leads me to the surmise you have the (mistaken) idea that: 1) you imagine that somehow you can make the current somehow less offensive to the inductor, a component that only has its electromagnetic field properties due to the application of the current you want to sneak past it; and 2) that is is desirable to do that, even if you could.

It is the purpose of the inductor to create a magnetic field that will oppose changes in the electrical field to a greater or lesser extent, according to the value selected when designing the circuit. Why would you want to make that opposition less? It would mean you’d be changing the value of the inductor which you could do by choosing a different one.

To answer your efficiency question, if this speculation is correct, it would make it less efficient in direct proportion to your “success“ at making these “spiral loopies” ”work”.

An inductor resists change in the current through it. How can a current resist itself?

That explains a lot. But just to be sure, more clearly, the idea would be that the magnetic field generated by the current that simulates an inductor, added to the magnetic field of the inductor itself, would have a significant increase in the intensity of the total magnetic field, right?

No. The magnitude of the magnetic field generated by any given inductor is proportional to the current passing through it, nothing else.

They may be to you, but both are rather nonsensical and have no specific technical meaning.

Please draw and share a graph of current spiral loopies. I would expect the horizontal axis to be time and the vertical axis current, but graph it any way you want.

Edited to add: If I understand what you are saying, I believe it can easily be made into a free energy device. Your “more efficient” creation of a magnetic field should be able to create more power than the input in a coupled inductor.

Edited again: A myth is something false that is commonly believed. So I think we can say safely what we are discussing not a myth.

It is good that you have ideas. But we no longer live in the middle ages where you would describe a waveform with a verbal description. But utilize instead an engineering and mathematical description.
Thereafter, you utilize the WELL KNOWN electromagnetic principles to analyze such waveform.

What? His scheme relies on making spiral loopies of current. None of us know what that is. I am asking for clarification. If you think I am implying that I think his suggestion is valid, you have read me very wrongly.
