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 😜
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.
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!
one of the funnest thing you can ever see is a bunch of 12-13 yr olds in a physics exam all trying to work out twisting their hands around bizarrely trying to orientate them to diagrams when thy reached the induction and motion section,
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.
