Is having a distracting animation of lightning at the top of this page appropriate for electromagnetism? that animation would be better on the lighting article and certainly not at the top of any page. — Preceding unsigned comment added by 124.176.51.109 ( talk) 07:06, 13 December 2012 (UTC)

This article, being a gateway, should have some illustrations. I agree that the lightning bolt animation is very distracting, and a image of a bar magnet doing notiong is of no value whatever. I kind of liked the idea of a static lightning bolt, but I'm not sure what its point is relative to electromagnetism. Given that, are there illustrations that would be useful, e.g. a photo of "lines of force" around both a bar magnet and an electromagnet made with iron filings (the point being that electric current makes "magnetism", and this is the same "stuff" as a bar-magnet's "magnetism"), and an equivalent electrostatics photo-image? (Good luck creating that one!) An electromagnet hanging by thin wires in a gravitational field (like a pendulum) and being pulled sideways by another electromagnet? (Easy to do). Ditto for a tinfoil-covered styrofoam ball being repelled by a charged plate? (Not so easy; this one I found as a problem in a physics text in a chapter on the electric field -- to calculate the angle from vertical; cf Sears and Zemanski 1964:564 problem 25-11, also p. 538 problem 24-4). As a kid I learned about "magnetism" from iron-filing making lines of force, and the experience that two magnets either repel or attract. Electrostatics I learned from charged balloons repelling or attracting, and scuffing my feet to make sparks (and to light up a neon light). That they are equivalent "stuff" in different forms is not a trivial factoid -- what you'd need to illustrate the idea is a triboelectrically-charged leaf-electroscope hooked to a Leyden jar that, when discharged through a coil of wire, moves a compass-needle. Thoughts? Bill Wvbailey ( talk) 15:39, 21 February 2013 (UTC)

I was wondering since people like Tesla and troy reed made electro-magnetic vehicles, and I did recently to add a small section on its historical accuracy. TBh, there are a few dozen inventers. Electro-magnetic car inventors are actually in yildiz, troy reed, wasif kahloon, tesla are a few of them. They work with plasma or a highly advanced form of hho (a battery system) with electromagnetic induction motors even. — Preceding unsigned comment added by 69.255.25.193 ( talk) 20:55, 6 July 2014 (UTC)
One of the design's problems has been antennas in the circuits. However, a team of researchers in university of Cambridge have invented a new way and is to integrate the antenna on the chip. last frontier of semiconductor design would be a massive leap forward for wireless communications.

Wikipedia says: "The electromagnetic force is responsible for practically all phenomena one encounters in daily life above the nuclear scale, with the exception of gravity. The electromagnetic force is also involved in all forms of chemical phenomena".
If I sit in a phycics or chemistry class, and watch my teacher do some physics and chemistry demonstrations, are 100% of them explained by electomagnetic force & gravity? (At high school or university).
You can assume my teacher does not own a nuclear reactor or a particle accelerator.
If there are important exceptions, please tell.

Since I can edit: the text of the Pauli exclusion principle in the section on fundamental forces is linked to the article about the Heisenberg uncertainty principle, not to the article about the Pauli exclusion principle. As I assume this is wrong maybe some of the priviledged editors can correct this link. 2601:280:4B00:590D:49DD:4267:E71:58E6 ( talk) 19:41, 26 June 2019 (UTC)
I've noticed that we have two articles with very similar title and content: electromagnetism and classical electromagnetism. Neither is in a good state, even though they are rather important articles: electromagnetism has about 30k views per month! I wonder if merging the articles could help concentrating effort into improving them? I assume electromagnetism is supposed to cover more than just classical electromagnetism, but it doesn't do it. Quantum electrodynamics is not even mentioned! Tercer ( talk) 14:49, 11 January 2021 (UTC)
Sorry I'm new so I don't know how to format very well.
In the page it says: "While preparing for an evening lecture on 21 April 1820, Hans Christian Ørsted made a surprising observation. As he was setting up his materials, he noticed a compass needle deflected away from magnetic north when the electric current from the battery he was using was switched on and off. This deflection convinced him that magnetic fields radiate from all sides of a wire carrying an electric current, just as light and heat do, and that it confirmed a direct relationship between electricity and magnetism."
If you look at Hans Christian Ørsted, it says that this is a myth, and that Hans discovered it on purpose. — Preceding unsigned comment added by Cal8205 ( talk • contribs)

I want to edit the part where electromagnetism is compared to the other four fundamental forces, as I fear that it is quite ambiguous in explaining that only the gravitational force is the other force operating at infinite range, and my edit will clarify this ambiguity.It is a minor edit adding only that one point.The text that will be added is- The only other fundamental force apart from electromagnetism which operates at an infinite range is the gravitational force.

In the first paragraph of the article, 5th sentence "Electromagnetic forces occur between any two charged particles, causing an attraction between particles with opposite charges and repulsion between particles with the same charge, while magnetism is an interaction that occurs exclusively between charged particles in relative motion.", the first word ("Electromagnetic") should not be instead "Electrostatic"?
