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

Click For Summary
SUMMARY

This discussion explores the concept of creating an inductor using capacitor plates arranged in series, leveraging the magnetic field generated by displacement current rather than electron current. The participants analyze the implications of having a larger gap between the plates, suggesting that this configuration could enhance the magnetic field produced between the plates and potentially reduce the effective resistance of the setup. The conversation highlights the limitations of traditional capacitor designs, which typically utilize conductive strips wrapped with insulating film, rather than expansive flat plates.

PREREQUISITES
  • Understanding of electromagnetic theory, particularly displacement current
  • Familiarity with capacitor and inductor design principles
  • Knowledge of resistance and current flow in electrical components
  • Basic concepts of magnetic fields and their generation
NEXT STEPS

  • Explore advanced capacitor designs and their impact on electrical performance
  • Investigate the relationship between plate spacing and magnetic field strength
  • Learn about the construction and efficiency of inductors versus capacitors
USEFUL FOR

Electrical engineers, physicists, and hobbyists interested in innovative electromagnetic designs and those looking to optimize the performance of inductive and capacitive components.

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)?
 
Physics news on Phys.org
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.
