Understanding the electromagnetics of real capacitors
by Asem Elshimi, Design Engineer, IoT Wireless Solutions, Silicon Labs Confession: For the longest time, up to my senior year in electrical engineering school, I thought you could find a capacitor on its own. I had such a boundless imagination to think that you could find a circuit element that is purely capacitive in behavior […]
Does a charging capacitor emit an electromagnetic wave?
Charging and discharging a capacitor periodically surely creates electromagnetic waves, much like any oscillating electromagnetic system. The frequency of these electromagnetic waves is equal to the frequency at which the capacitors get charged and discharged.

How to make an electromagnet: A Guide for Beginners
This guide aims to demystify the process of creating an electromagnet at home, making it accessible for beginners and enthusiasts alike. By carefully following these steps, you''ll not only build your very own electromagnet but also deepen your understanding of electromagnetism''s principles.
capacitor
And make sure you have a capacitor across + and - to deliver enough current, and it''s as simple as that. Here is my very thrown-together electropermanent magnet using a cylindrical N40 grade rare earth magnet and a square bar AlNiCo magnet I found online, and two steel hex bolts as the iron keepers, resulting in something reminiscent of a horseshoe magnet:
Capacitors Basics
What are capacitors? In the realm of electrical engineering, a capacitor is a two-terminal electrical device that stores electrical energy by collecting electric charges on two closely spaced surfaces, which are insulated from each other. The area between the conductors can be filled with either a vacuum or an insulating material called a dielectric. …

Combining a ferromagnet with an electromagnet can produce particularly strong magnetic effects (Figure (PageIndex{5})). Whenever strong magnetic effects are needed, such as lifting scrap metal, or in particle accelerators, electromagnets are enhanced by ferromagnetic materials.
Using AC or DC to create an electromagnet
A quick footnote to Anna''s comment: When you specify a voltage for AC this is usually an average voltage not the peak voltage. Anna is quite correct that e.g. 100V DC will give a stronger field than 100V AC if by this you mean the peak voltage is …
