_______________________________________________________________________
In 1822 the British scientist Michael Faraday, working at the Royal Institution in London, created the first electric motor, where an electric current was used to produce motion. The story goes that he made his discovery over the Christmas period, possibly on Christmas day. His version involved a wire dangling in a glass vessel filled with mercury, and he is supposed to have said 'there they go' when the motor started working.
Many years later, one of us (George Auckland) wanted to recreate this experiment for a television programme. Bill Coates, who was a 'science communicator, lecturer and technician' who worked at the Royal Institution, was given a mince pie by his wife on Christmas day in 1986, and he realised that an aluminium mince pie case together with a strong saline solution could replace the use of mercury in the original experiment.
Tim demonstrates this modern version, and in the middle of the pie case he is using a neodymium magnet, which of course is stronger than the original magnet that Michael Faraday would have used.
The battery is connected to both the pie case, which is sitting on a piece of aluminium foil, and the other terminal is connected to the wire that is holding the moving piece of wire that hangs down into the salt solution. The salt solution conducts electricity, which completes the circuit, and the wire revolves around the magnet. Reverse the direction of the current and the wire revolves in the other direction. Turning the magnet the other way up also reverse the direction that the wire revolves.
This motor didn't generate any useful power, but it demonstrated a principle, and it was not long before more useful motors were developed.
Fleming's left-hand rule, which Tim refers to, can be used to work out which direction the wire will move in.
Michael Faraday's subsequent discoveries included the induction coil or transformer, and also the generator. He effectively laid the foundations for the modern discipline of electrical engineering.

Not only are these videos filled with weird and quirky toys but also very educational. Bravo! Truly extraordinary!

Here I see that I’ve been traumatized by @electroboom videos, as my ears began ringing before I realized the setup was inoffensive and safe, indeed.
Joined watching this channel back in 2010, and I'm always amazed at what you have to show. Fun toys of history and even toys from my childhood that I had forgotten. Just want to say thank you Tim and your crew for the years of amazing videos and for bringing light to fun forgotten history. Thank you
This guy always reminds me of the best kind of Professor, the kind that knows everything there is to know about his field, knows how to and loves to convey that knowledge and casually rips jokes on the side, I love that energy!
I recall an edition of The Eagle magazine annual from the late 1960s or early 1970s which had all sorts of things to do, including an electric motor with an armature etc, but this Faraday motor is much better to my way of thinking, as it's so much simpler and demonstrates the original principle itself. Marvellous! Thanks Tim. 🌟👍
Almost 100% accurate. The true first electric motor used mercury instead of a saline solution, but ofc a saline solution is much safer and easier to obtain 😜
This intro is SO CUTE!
oh my.. I used to watch this channel several years ago.. tim you look still good!!! and the wow thingy still makes me wow. why did i forgot here
Tim now shows his nerdiness and geekiness. Such an amazing guy.
Good presentation, Tim.
I just finished my physics final on electromagnetism this is giving me PTSD o.O
It's like Mr. Wizards world all over again!
Also if you light a match next to the water it will go boom. Presumably.
This is so cool and educational.
Would love to see more experiments
Also left hand rule in maths. Thumb x index y middle z. So when you see me staring at my thumb in truly plotting something devious 🙃
We still invent plenty of amazing stuff, but there's something special about doing it with simple components like this and not circuitry and all that.
Thank you Tim ❤
I was having trouble finding copper wire, so I threw a penny onto the pavement outside my local synagogue
Reminds me of the awesome motor Rex Garrod made on "the secret life of machines". Always wanted to make one of those!
Wonderful and intresting video.Wonder what else Faraday used his new invention for.
Really cool video! :D
The middle finger is for B field The thumb is reserved for a force (or motion in this case) The index finger is for current You hold the fingers in this pose If two fingers match their vectors You know where the third one goes!

Remarkable to think that humanity went from the invention of the very first electric motor to going to the moon in about 150 years.
Faraday motor ! :) No practical use but a big step ahead for industry ! :)
I used to make similar, simpler electric motors for my cousins when they were really little. I'd attach a few circular magnets to the bottom of a AA battery and on top set a copper wire that was bent around to make a v which touched the positive end of the battery, from the v were two arms that came down the side of the battery and just hovered in the magnets field. When you let go the wire would spin around really fast.

And since you are not using Mercury , you could use a match and show electrolysis at the same time, two for one.😮

I think Faraday did it with mercury, so, yes. Although magnets would float in mercury. That would be a problem.
Amazing!

For an intelligent guy, he sure does pronounce a lot of words incorrectly. 😂 Serioiusly though. I loved this. Great video.

For motors and generators, there are both left-hand and right-hand rules. The left-hand rule applies to motors, and the right-hand rule (with the fingers labeled the same way) to generators. This makes sense, since a generator is just a motor working "backwards," with rotational motion creating electric current, rather than electric current creating rotational motion. The more general mathematical rule for determining the direction of a cross product is, by historical convention, a right-hand rule, but that's probably just because more people are right-handed. You could easily formulate it as a left-hand rule.

interesting. society should have grandiose celebrations regarding such technological developmental anniversaries. but we're too brainwashed to focus on apparitions and myths instead of useful knowledge we could use to form independent lifestyles apart from the capitalistic agenda.

What is this minced pie he's talking about in the first 30 seconds? What material or element is that? Is it also aluminum like the aluminum foil? It would be greatly appreciated if anyone has any insite into this.

A mince pie, also known as a mincemeat pie in North America, is a small sweet pie filled with fruit and spices. Traditionally eaten around Christmas time. They are always in a small aluminium pie case.
