The correction is rather simple: In the past I always said that those old televisions run on something like 50 thousand Volt. That is of course the kathode electric potential and not your input voltage. That is not entirely correct: all photo’s I showed you in the past were made with a small television set and those seem to need a lower kathode voltage. May be something in the 25-30 kV range.
So that is a small correction but I have written posts where we tried to calculate the sideway acceleration and I based the speed of the electrons going from the electron cannons to the glass screen on the 50 thousand Volt. I memory served that gave a giant speed of almost one third of the speed of light and that gave giganormous numbers when it came to sideway acceleration. If indeed those small tv sets run on a lower electric potential, that was a bit over the top.
Well that does not impede the fact that electrons are likely magnetic monopoles and not magnetic dipoles as the standard model of physics says. So far for my correction on past statements.
I am still having a bigger television and I finally made a few photo´s of the behavior of electrons with that oldie. It is best to make those pictures in a dark room so that your camera has a relatively long shutter speed. I tried it once at daylight outside but that gave lausy results because in between the rereshment of the screen it often is black because no electrons have landed there recently. If you take photo´s in a dark room it gets better. When I looked with my human eyes to the television without any magnets around, I see a clear blue uniform is color and intensity everywhere. In the next photo you see how the camera ´sees´ it. Not very uniform…
In the next photo I come in from the right with a stack of magnets. It is amazing from how far away the screen already starts changing.
In the above photo you likely see already the separation of the ´blue´ electrons in those that are attracted by my stack of magnets. That should be the blue spot on the lower right. The other blue region should have at it´s right lower boundary mostly repelled electrons while that large blue region could also contain a lot of electrons that are not disturbed enough.
Ok, the next photo is more important because even at 50 thousand Volt with the relatively sharp tip of my neodymium magnets you get that dark disk where no electrons land. So we have a clear separation of electrons that are attracted versus those that are repelled by the magnetic field from the stack of magnets.
Remark it is very hard to explain the dark region where clearly no electrons land with the Lorentz force. The standard model has only this Lorentz force in it and ok ok they also use that weird term for the potential energy for an electron in an inhomogeneous magnetic field but in my view that is not correct because it does not include the size of the electron. And by the way, it should be a cakewalk to separate the electrons according to their spin using magnetic fields that are as uniform as possible. There are still plenty of those in physics labs all over the world, if electrons are magnetic monopoles it should not make much difference if you use a uniform or non/uniform magnetic field.
In the last photo I turned my stack of magnets around. On the other side I often have 2 or 4 ring shaped magnets that I removed from two magnetron ovens. They have a hole through the middle and I tried to photograph it such you can look through that very hole.
I hope you see that tiny spot in the middle where the attracted electrons create a while light. Ok that was it for this update. In the meantime I am working on a post around the sphere/cone equation written in matrix form. But that is far from finished so see you somewhere next month!
Today was a good day because I scored 80 kg of malt and almost one kg of hops so I can brew for a long time… Upon arriving home there was an envellope on the doormat, is it what I hoped for? Yes it was, a new compass. I bought it two days ago and it costs only 8.50€.
Yesterday I made a permanent magnet and the new compass says it actually is a real bipolar magnet (made from an iron nail). For me that was a nice historical moment because it was the very first time that a human made a permanent magnet that was solely based on the principle that electrons are magnetic monopoles…
The Curie temperature is that temperature where ferro magnetic materials like iron loose their magnetic properties. But what does that mean? That means two things: A permanent magnet gets destroyed, it is no longer a permanent magnet when it becomes too hot. And the second surprising thing is that a piece of hot iron above the Curie temperature is no longer attracted by a permanent magnet. Let me repost two photo’s on this website to make the point clear. In the first photo you see an iron nail attracted by a small stack of neodymium magnets, I heat the nail up with a simple burner and all of a sudden the nail is no longer attraced. That is what you see in the next two photo’s:
Ok, how to make a permanent magnet with only a small stack of neodymium magnets? Very simple: I hanged the nail a bit higher and placed my small stack of neodymium magnets under the nail. About 2 mm of distance between the tip of the nail and the magnets. And you burn the nail until it is hot enough. After that you just let it cool down and voila: you have made yourself a permanent magnet using only idea’s derived from electrons being magnetic monopoles.
Ok, that was it for this post. See you in the next post.
Update from 13 Sept: My nail magnet is so weak you cannot lift other nails with it. It works fine because a compass reacts to it but it is not very strong. On the other side of the spectrum I found a cute video today where they claim to have achieved a magnetic field strength of 20 Tesla…
The video is from Tokamak Energy, that is one of those startup companies that try to craft workable fusion reactors for commercial electricity production. Like explained before: if indeed electrons are magnetic monopoles and because they react much stronger to the applied magnetic field compared to the plasma protons, this will cause a ton of turbulence. And stronger magnets do not solve that problem; on the contrary the turbulence will appear much sooner in a stronger magnetic field.
You may hope that the university people finally pop up some kind of proof that electrons are indeed magnetic dipoles. But it is now Sept 2019, the start of a new academic year. And to be honest I don’t expect such a proof this year. So in the meantime while the climate is changing, lot’s of people dream about nuclear fusion as an energy source and the university people will do nothing day in day out this new academic year.
From a video from 5 June this year where Tokamak Energy promotes itself by pointing at the climate change I made this small screen shot:
Here is the video I found today: if only electrons were not magnetic monopoles it would be a great find. Ok, end of this update.
