How an Electromagnet Works and Why a Shoemaker Invented it

- Why did a shoemaker and retired soldier named William Sturgeon invent the electromagnet and how does an electromagnet work anyway? Watch this video to find out!
As usual thanks to Kim Nalley for the fabulous singing. - Наука та технологія
Thanks, Kathy! Your videos are so educational and engaging! I guessed that you had taught physics for some time before starting your video series. So, I Googled you, and found that you've taught both high school and university physics. Your students must love your classes! I really like your historical approach to teaching physics. It allows the learner to follow the path of discovery, and to see how each subsequent breakthrough occurred.
What a great find!
I was looking for a diy for Sturgeon's electromagnet.
As you know,
your an excellent teacher.
Thank you.
If I may,
your presentation, your enthusiasm, your vibe although invisible, can be felt registered and therefore its concluded, that your electromagnetic radiance,
during your presentation, draws in people of all walks of life and not necessarily fans of physics but your energy harmonize perfectly with a natural perfect logic,
thereby elegant and sweet, in open arms.
Forgive me, but if I may..."You're an excellent teacher."
Thank YOU madam, for YOUR lessons AND a glimpse of HISTORY, that is the icing on the cake.
ONCE again, I THANK YOU for the piece of human "ACHIEVEMENTS" you are showing ALL.
"WE the people" HOPE to deserve the HISTORY.
VERY glad that I discovered this channel.
Respect, FROM India.
You are quite welcome
Great vibes
These old lithographs with period printing and just making such discovery after discovery. More like magic than anything we have.
Thanks alot for the nice topics you share , I really enjoy a daily dose of your channel.
Thank you for the great videos
Someone should give you an award for this!
I feel like I just won an award because of your lovely comment. Thank you.
👏👏👏👏👏👏👏👏👏👏👏👏👏👏.
I love your enthusiasm and there is nothing sexier than a smart woman. I'm enjoying your videos.
In reading Faraday’s notes, Article 9 at 3:10, it is so interesting to me his humility; I only hope I present myself in a similar fashion, he’s very inspirational. I should like to find an anthology of his written work, I think it would make for very good reading. I can easily see how he made such notable contacts, I can only imagine what a pleasure it must have been to work and correspond with such a gentleman.
It is amazing to me he came up with the theory of a magnetic field surrounding a current carrying conductor, especially given the trouble I had conceptualizing the various fields in college Physics - and those had already been discovered and/or theorized! It’s a huge mental leap to theorize something as such from scratch, all from primitive experimentation and outstanding deduction. He’d been quite the fellow to have a cup of coffee with. As before, thank you for sharing your love of Physics and history, Kathy.
Love that right hand rule 👍
You've made some of these things! SHARE how ya did it, or at least how we can do it safely.
I've been enjoing many of your vidoes (all those I've seen). I do have a question of fact about one item in this video. Wasn't the first telegraph the Cooke & Wheatsone system?
was video so great to use reworded stuff for my english paper
Glad it was helpful!
7:30 young Samuel Morse looked like Jordan Peterson.
On e I get my lab up and running after a move, I’ll try it - but - what happens if you wrap a current carrying wire around, say, a bar of aluminum rather than steel (or cobalt, nickel). I know eddy currents get generated, but will it concentrate the magnetic field lines and will it attract ferromagnetic materials?
Oh, his hair and sideburns were definitely "dramatic and inspirational" as well. 😅
mmmm, electromagnetism, love it.
another great video of yours. I m just an interested layman. I watched a video that showed : because the electrons flow with the speed of light Einsteins theory of relativity comes into place by the electrons gaining more mass and are producing therefore more magnetic attraction as anticipated, and what does this to time because if time slows down the speed slows down too ? Explanation ? I don t get it ?
I am sorry I don't get it either.
The electrons don’t move at the speed of light - they can’t, as they have mass. However, the effect they manifest can.
When you really think about it, the quote, "Advanced-enough technology is indistinguishable from magic" is actually not quite right. Electromagnetism IS magic, as far as the basic definition is concerned!
"Magic" has its only difference in having the person doing it have some sort of direct or indirect control of the actions of some object, including living things, or summoning up some being that has such ability that will do its thing when the magic-user requires it (forced, bribed, or payed-for). "Electro-magnetism" as a source of energy and controlled force is different only in that it has a physical form that can be built-into objects using manufacturing techniques similar to those of a blacksmith (taking the proper rock and extracting the iron and then mixing it with heat and other materials in the correct way to strengthen the final object, such as a sword, for some purpose). Once known, anyone with the knowledge, resources, and enough skill (and usually assistance in a group project) can create the device that performs the "magical" activity. And the things electro-magnetism can do or are involved with in our world are magic as far as their huge variation, including chemistry, biology, power generating, power directing, communications, computation, and so forth,. ad infinitum.
There is NO difference between electro-magnetism and magic as far as the possible results are concerned, just more repeatable, down-to-earth rules governing these created results...
i want to set up an historical electrical invention lab, i hope you may help me.
Of course, just send me an email (in my about me) and I will help however I can. (Sounds exciting)
@Colin Mitchell yes you are right
@@Kathy_Loves_Physics hi Kathy can i have your email id
@@Kathy_Loves_Physics hi i have sent you a message in your email
wow thanks for mentioning Samuel Morse's racist egotism, it helps to contextualize historical figures in all their glory and sin, I wish historians would do this more
Of course, the details of people's opinions are what make history interesting IMHO
A lot of people have a dark corner in their loft
gasp... another Thomas Edison...
I was enjoying this series until you called Samuel Morse a "Racist Egoist" . Where do you get off judging people who lived in another time by calling them present day idioms? You lost all credibility with me in that statement. You have no right passing judgement on someone who lived in another place and time! Unless you were there and knew all the circumstances on which you base your judgement, you have no right to pass judgement. Keep your opinions to yourself!
Samuel Morse was ardently pro-Slavery, anti-Catholic and anti-Irish. The was called a racist egotist in his OWN time.
@@allangibson2408 Your sources.
@@JohnMGilbert en.wikipedia.org/wiki/Samuel_Morse
It’s not exactly a secret.
@@allangibson2408 Glad he was the only one.
You say judgement a lot
Having a theme song that just repeats the same word over and over at the beginning and end of your video is extremely annoying. It's not a cute song, it just gets stuck in your head, and so I will not be watching your channel, even though it was good otherwise. I'm not exposing myself to that kind of psychological warfare that tries to force things into my mind by repeating them over and over.
Bye. Don’t write.
Adios Don’t let the door hit ya
