An electromagnet made of a bunch of capacitor plates in series?

AI Thread Summary
The discussion explores the concept of creating an inductor using capacitor plates arranged in series, focusing on the magnetic field generated by displacement current rather than electron current. It raises questions about the magnetic field distribution, suggesting that most of it would occur between the plates rather than around them, potentially reducing resistance. The participants speculate on whether this configuration could allow for higher current handling capabilities compared to traditional wire coils. Additionally, the design of capacitors is noted, emphasizing that they typically use conductive strips rather than expansive flat plates. The conversation highlights innovative approaches to electromagnet design and their implications for electrical resistance and current capacity.

Has anyone every tried to make an inductor made out of capacitors, that is to say, which uses the magnetic field of displacement current rather than that of electron current to generate magnetic fields? Let's say the gap between plates is greater than the thickness of each plate. Wouldn't most of the magnetic field be produced between the plates in this case, and not around the conducting medium of the plates themselves? Wouldn't this help to reduce the amount of resistance of plates for a given material, path diameter, and (effective) length? Would the effective resistance of such a coil be reduced signficantly? Would it be able to handle higher currents for a given diameter (of plates, rather than wires)?

Capacitors of significant value are not constructed with expansive flat plates in parallel planes. They are made using conductive strips with an insulating film and all wrapped around tightly together.

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
