Something that looks like an electromagnetic coil on a motherboard, or like a Warp core (an interpretation which I prefer, of course), but is an entirely "analog", very simple, everyday stationery item: A stainless steel pen clip that consists of a strong clip to which a flexible spiral that holds most thinner pencils or pens is attached (so it would have worked for last week's theme as well, but it hadn't been on my radar then). For completeness, I've added a blue aluminium Rotring ballpen that, at some point in its desk life, "lost" its clip (it came loose at some point so I decided to remove it). Colour light helpers were the usual suspects, and I've processed the image in DXO, Color Efex, and Analog Efex, with final touches in LR, which seems to be my preferred processing workflow at the moment.
HMM, everyone, I'll catch up with you tonight!
Is electromagnetic radiation and we generally refer to that which is visible to us. Light is transmitted in the form of waves whose reflection illuminates surfaces, thus allowing us to see objects and colors around us.
The tiny snail loved Physics lessons! She particularly enjoyed studying the electromagnetic spectrum, and the idea that the different colours of visible light had different wavelengths - although it took a while to come to terms with the fact that blue light had the shortest wavelength and red light had the longest wavelength - but with perseverance she was able to get on top of the subject material.
For Macro Mondays theme 'Wavy Lines'. The coloured wires were arranged and photographed to be within 7cm.
No snails were harmed in the making of this photograph.
A very severe solar electromagnetic storm hit the National Gallery of Australia, Canberra area last Saturday. The area was totally depleted of colour, except for red. The ACT Police, Missing Colours Unit, is investigating and has not ruled out alien intervention. This is all very strange but has happened in this area before.
I saw this wall lamp in the one of the rest rooms of the restaurant Chambard in Kaysersberg, Alsace.
So I had to return and take a photo (or 2)

Buckyballs are a great way to illustrate magnetic attraction and repulsion. The bowl is also magnetic. it's actually for your change.
Photographed at the Railway Museum in Utrecht, this electric locomotive bell showcases the functional elegance of early industrial signalling. Unlike the traditional steam‑driven bells, this type uses an electromagnet and mechanical striker, a system widely adopted in rail environments from the late 1800s onward. In black and white, the polished metal surfaces and the precise engineering of the mechanism stand out, highlighting both its utility and its craftsmanship.

The visible spectrum is that part of the Electromagnetic spectrum that human eyes can perceive and experience. The visible light spectrum, 380-740 nammetres, gives plants the ability to photosynthesise, fix sugars in their green leaves with cholorphyll and chloroplasts, thus feeding the world around us.
So a great idea David Nice to pick Light for this month's FOTF theme. (Explored)

Like all kinds of electromagnetic radiation. However, in the case of light, we can see the effect this particular kind of radiation has on materials and surfaces (reflections for example). And "seeing" is the brain's translation of what happens to our retina when light enters. The literal meaning of "photography", an artificial term just 200 years old, is "writing with light". We don't. We can't even see light. Our camera is rather a tool to organise and influence our brains' translations of the impact of light. Photographers are translators, not creators in a strict sense. However, there are good and bad translations. Sony A7iii, Pentacon 3.5/30.

Please zoom in to see all!
There are 4 fundamental forces (gravitation force, electromagnetic force, strong nuclear force and weak nuclear force) in our universe. Without them, our universe will not exist. The strong force is the strongest of the fundamental forces. It holds together the protons and neutrons in atoms. The weakest of the 4 basic forces is gravity. Every atom creates its own gravitational field which attracts all other matters in the universe.
In other universe, similar forces could be in effect to create different building blocks from tiny particles. These fundamental tiny-particles are created after big bang. The tiny particles, quarks, build protons and neutrons which make up the nuclei of an atom. In another universe, quarks might not form protons and neutrons. Without them, we will not have atoms.
Another universe might also be an atom based universe like ours. In that case, this one would be not very different from ours. It would have same processes to create things. It could have cities like ours.
Endless space might have some smiler universes (smiler to our universe). Without fundamental forces, there will be noting. Similar fundamental forces would create similar universes.

Un temporale lontano. Lampi improvvisi illuminano la notte. Sullo sfondo, un cielo blu scuro, cobalto, punteggiato di stelle lontane. Eppure la luce è la stessa, increspature di energia che si muovono ad una velocità inimmaginabile... e pur provenendo da mondi diversi, il mio occhio le sente, le registra insieme, il cervello le interpreta come luce... e io non posso che restarne affascinato. Profondamente.

Electromagnetic coils on an old graphics card.
From the basic electronic components I always found the coil the hardest to understand. In addition to the invisible current you suddenly also have this invisible magnetic force (flux). But it's a beautiful component making it a nice subject for this week's theme.
Thanks for all your comments and faves, they are really appreciated. Happy Macro Monday!

Demonstrating electromagnetism is way beyond my ability, so I went for straight magnets. I remembered I had this Magnet set from many years ago, so I went rooting in my upstairs closet and found it. The sticks all have strong magnets on each end, and the balls are steel. I had bought several sets, and my husband, grandson and I had a lot of fun building complicated structures with it. It’s a bit addictive. I’m glad we are limited to 3 pictures per challenge, or I would still be building!

Really chuffed to have gone out to watch the Aurorae with Miss Informed tonight. Until now, the best I'd ever seen was a couple of indistinct glowing blobs in the night sky, but tonight was, for the Northern Lights, what the crystal-clear skies of Australia have been for my viewing of the stars.
Things started off quite tame, perhaps overly so until our eyes adjusted, but soon we had half a sky of sorcerer's colours, transiently draping down in curtains and also occasionaly booming across the sky in bows and waves.
Truly a stunning phenomenon to observe.
Exchanging Electrons with the Electromagnetic Field.
How does a Plasma Ball work?
Inside the globe, there is a high voltage electrode, which is powered by a Van de Graaff generator. When the electrode is energized, it creates an electric field inside the globe.
The electric field ionizes the gas molecules, stripping electrons from the atoms and creating a plasma. The free electrons accelerate in the electric field and collide with other gas molecules, causing them to emit light. The patterns of light that you see in a plasma ball are created by the movement of the electrons and ions in the plasma.
In this case, the Noble gas in the ball is 95% Neon and 5% Xenon.

It’s no secret by now that the little red dwarf that makes our lives possible has been very electromagnetically active lately. In 2024 and 2025 there have been several events leading to Aurora Borealis visibility all the way to at least the southern USA. On November 11, 2025, a powerful X5-class solar flare (the strongest of the year through that date) plus a fast CME hit Earth’s magnetosphere, triggering a rare G4-level geomagnetic storm. I’m not geeky enough to know exactly what all that means beyond knowing that a G4 storm is getting strong and triggers strong aurora.
On that evening I had heard nothing about the event and was getting ready for bed when a last glance at social media showed me several posts from the southeast, including Arkansas, with vibrant aurora images from just an hour earlier. Tired or not, I changed back out of my pajamas and took a short drive. Not having much time to plan, I went to a little spot alongside US 395 where the highway runs due north and set up a shot. The aurora weren’t naked-eye visible per se, but when I first got there I could see pink reflections in the clouds. This image is one of the earlier frames I shot when I could still see the auroras reflecting in the clouds and the camera rendered them very bright. I thought the headlights of an oncoming vehicle added a nice anchor point in the distance and gave some nice subtle lighting to the foreground
All in all, it was definitely worth pushing my bedtime back for.
A quiet stretch of US Highway 395 glows under the faint shimmer of a rare aurora, where the desert night hums with motion and light. The long exposure reveals ribbons of red and gold from passing traffic cutting through the stillness, framed by a sky charged with solar energy. This scene speaks to night travelers, stargazers, and anyone drawn to the intersection of nature’s mystery and human movement. A striking addition for contemporary homes, creative studios, or spaces with a moody or atmospheric design. Perfect for those who’ve driven the open roads of California or remember the feeling of chasing something beautiful just beyond the horizon.

The Lagoon Nebula (M8, Messier 8 or NGC 6523), is a giant interstellar cloud in the constellation Sagittarius. M8 is estimated to be between 4000 - 6000 light-years from Earth in the Milky Way Galaxy, and is classified as an emission nebula.
About this image:
Imaged in three key wavelengths of the electromagnetic spectrum of light (Hydrogen-Alpha, Sulfur-II and Oxygen-III), over a few nights (due to poor Astronomical seeing conditions, as a result of a very strong jet stream).
About Emission nebulae:
Emission nebulae are glowing clouds of interstellar gas which have been excited by some nearby energy source, usually a very hot star. The red light seen in this picture is glowing Hydrogen captured in the Hydrogen-Alpha (Hα) Infrared wavelength of light at 656nm. The blue light is from doubly ionized Oxygen ions (O2+) emitting at a wavelength of 500.7nm.

Flux density variations and charge field fluctuations of thermal enhancements of oil and water in a pan.
Wikipedia defines the "Electromagnetic Spectrum" as the range of frequencies of electromagnetic radiation and their respective wavelengths and photon energies.
The frequency of these electromagnetic waves ranges from below one hertz to above 10 septillion (10,000,000,000,000,000,000,000,000) hertz... with wavelengths from thousands of kilometres long... down to a fraction of the size of an atomic nucleus.
Although our bodies are constantly being bombarded by the entire electromagnetic spectrum... the average human eye is only able to detect the wavelengths between 380 nanometres and 750 nanometres. This is what is known as the "Visible Spectrum".
The rainbow of radiation that is observable to the human eye only makes up about 0.0035 percent of the entire electromagnetic spectrum. That's not very much at all in the grand scheme of things. I often wonder how much more interesting the world would be if we could see more of the electromagnetic spectrum.
So what has this science lesson got to do with this photo of a Yellowwood tree and a sun-star? Hah hah... absolutely nothing at all. :)
