Make Your Own Smartphone Radio Station | Physics with Professor Matt Anderson | M24-16

[@coax31]

I love watching your videos even the difficult ones covering physics with calculus. I am not even in college I am 48 and work in IT, wish I had professors like you when I was in high school and college maybe I would have been better at math.

[@plcogren9404]

Me too :) Except I am 42

[@magentadesign4009]

Me too: im 47

[@kushalsharma1792]

Me to but I am 19

[@yoprofmatt]

Thanks and welcome everyone. Most of these videos were shot when I was in my 40s. But now I'm in my 30s. At least that's what I tell my kids. Cheers, Dr. A

[@canobiggs]

Great example of an application, thank you!

[@yoprofmatt]

You're very welcome! Cheers, Dr. A

[@brentharlow4851]

It's like your teaching induces knowledge into us as students from a distance. Induction is king!

[@yoprofmatt]

Love a good physics pun. Thanks. Cheers, Dr. A

[@manla8397]

You should also try to insert an iron core to the centre to see how this can increase the flux coupling.

[@yoprofmatt]

Great idea. Cheers, Dr. A

[@samofohachinweuba1641]

Wow.. fantastic and great choice of music.

[@yoprofmatt]

Many thanks! Gotta love Marvin Gaye. Cheers, Dr. A

[@juniorcyans2988]

Oh, amazing! I love this! So cool!

[@shiqili3017]

Great video and great explanation!

[@7sArts]

Tesla would be so proud to see how far we’ve come. Taking a 19th century experiment and calling it a radio station doesn’t make it any less basic. Would be cool if you could teach us about how Tesla’s “method for transmission through the natural media” works, then again, only he and his team of engineers actually knew that secret, despite all the clues Tesla left behind, hidden in the text of his parents and the deposition for the Marconi trial. Keep at it Matt, someday we might catch up.

Terrestrial standing wave...

[@yoprofmatt]

Thanks, I'll try. Cheers, Dr. A

[@drjohn5407]

"Whats going on"... love the pun :-)

[@douglasstrother6584]

I wonder how many are hearing Marvin Gaye for the first time, thanks to Professor Matt.

[@yoprofmatt]

Now that makes me feel a bit old. But good. Cheers, Dr. A

[@abinetaragie2260]

Hey!! Can anyone please tell me how to do this at home.... like..... in details.... plsss

[@prashanthkumar0]

Awesome 🤘 ...

[@yoprofmatt]

Thanks ✌️and rock on! Cheers, Dr. A

[@quintonwilson8565]

real-life demonstrations are the best

[@yoprofmatt]

Agreed. I'd like to do more. Cheers, Dr. A

[@AdrianoBatti]

Nice thanks! Some good content!

[@yoprofmatt]

Glad you enjoyed! Cheers, Dr. A

[@XiahouKay]

Amazing !

[@yoprofmatt]

Glad you liked it. Cheers, Dr. A

[@florentinosanchez3969]

Awesome

[@yoprofmatt]

Thanks. Fun, right? Cheers, Dr. A

[@fougamagister8862]

great!

[@yoprofmatt]

Thank you. Cheers, Dr. A

[@definty]

That is the coolest lowpass filter iv'e ever seen. Atleast I think its a lowpass? it sounds like one

[@yoprofmatt]

Sounds like one to me too. Complicated lowpass, but quite fun. Cheers, Dr. A

[@coax31]

When the metal sheet passes between the coils and interrupts the signal is that the basics of RADAR?

[@yoprofmatt]

I would say yes. The metal will reflect the EM wave, whereas the plastic will not. RADAR essentially works by sending out a strong radio EM wave and looking for reflections from ships, airplanes, etc. (which are made of metal). Cheers, Dr. A

[@fsiserir]

Thank you for this interesting video which will help students to know more about the basic induction and coupling flux , magnetic flux , transformer.

[@yoprofmatt]

You are welcome. I think it's a fun little demo. Cheers, Dr. A

[@shannonmonaallathat]

Super 😎 smart and trendy crowd up In here

[@yoprofmatt]

Definitely smart, but I'm not so sure about trendy. Unless you mean dorky. Then yes, we're very dorky. Cheers, Dr. A

[@shannonmonaallathat]

@@yoprofmatt me being here Made it Trendy! So there..both 🙂

[@layicorn]

🐐

[@fizixx]

Figured you for a Marilyn Manson kinda scientist! ha ha ha ha.....GREAT application of this. Demos rock! It really drives-home the ideas and concepts to the Muggles (non-science folk)! 😁

[@douglasstrother6584]

... or Rush.

[@yoprofmatt]

Both excellent suggestions. If I was super cool, though, I would have used Vulfpeck "1612": kzbin.info/www/bejne/oIOrgoN9Zt2Xb9E Cheers, Dr. A

[@fizixx]

@@yoprofmatt Wow...what a blast! Great sound. You may like, The Surfrajettes --- this tune: kzbin.info/www/bejne/kHLclomgo6-ab6c

[@Sean85Laney]

Can you make a stator for a motorcyle???

[@yoprofmatt]

I can't, but apparently it's pretty common: www.revzilla.com/common-tread/what-is-a-stator Cheers, Dr. A

[@davidhilton7780]

Add an aerial and earth with some foil for capacitor...

[@yoprofmatt]

Great idea. Cheers, Dr. A

[@vostoks1203]

Greetings from turkey teacher, if we made more thick solonoid"idk how it s writing" can we reach more range and pure sound? It s first question, Whats happen if distance = 0 between of 2 solonoid

[@yoprofmatt]

Thickness of wire won't affect much. A thicker wire gives you less resistance, but it also can't be wound as tightly. If distance = 0 you get good sound because the magnetic field from #1 is fully intercepted by #2. Cheers, Dr. A

[@sdriver82]

Power to speaker???

[@arnonroyna4420]

The speaker has a battery in it.

[@yoprofmatt]

Yes, it's a powered speaker. If you hooked it up straight to a speaker cone, you'd never hear the music. Cheers, Dr. A

[@danratsnapnames]

yea, i guess in the simple terms this could be a radio station. but in reality, NOT even close. its just a demonstration of magnetic inductance. easier to just toss an oscillator into the mix and use a switching transistor to switch based on voice, and create a voice modulated transmitter.. also known as an AM radio.

[@yoprofmatt]

Yep, just trying to keep people's attention. Cheers, Dr. A

[@harshbansal7524]

Sir, please make a video on Cavitation Please Please Please

[@yoprofmatt]

I'll put it on the to do list. In the meantime, here's one of my awesome colleagues: acoustics-research.physics.ucla.edu/sonoluminescence/ Cheers, Dr. A

[@nolandayne]

Very cool demonstration. If you want another cool demonstration to show people. Double slit experiment. Get a laser and very thin wire. Grab the wire and lay it vertically across the laser. (you can lay extra wire and then tape it in place around the handle) (The wire creates the two needed paths) ( | ) < Example of how the wire should lay over the laser. If done correctly, you can demonstrate the double slit experiment in real life flawlessly. I enjoy showing people my real life double slit experiment.

[@nolandayne]

I also think it would be wise to cut this into a 1 minute or less (KZbin really recommends less than 15 seconds to have the best watch time) KZbin short and use the shorts algorithm to grow your channel. Shorts algorithm is usually very positive if your watch time stays high. (Throws You on the shorts shelf more often I have noticed)

[@yoprofmatt]

Great tips, thanks. Cheers, Dr. A

[@DargiShameer]

Interesting

[@yoprofmatt]

Thanks. I agree. One of my grad students showed me this demo. Super cool. Cheers, Dr. A

[@sdriver82]

What if we used 144

[@yoprofmatt]

144 loops instead of 200? The amplitude would be cut down by 144/200 since you're intercepting less flux. Cheers, Dr. A

[@numistika]

That's the old school radio, I wish someone made quantum radio that transmits to the opposite sides of the world, and explained its physics. We need quantum radio badly for communication without satellites and on unmapped distance, particularly for such missions as Mars exploration. And just saving the nature. I would not be surprised to know that our brain is already pre-built with such receivers. ))))

[@danratsnapnames]

agreed, but good luck getting ahold of quantum entangled matter, being that its millions of dollars just to make one. then the next thing is trying to figure out how to entangle matter with some sort of switch, so that it could be controlled. right now, controlling quantum changes between the matter pieces is obsurvational at best,. not any good way to measure it at present. so attaching a switch to that entagled matter is not possible yet. but its not far off from doing such things.. . communication lag with distance would be a thing of the past, and drone operators could work at home with VR gear alone.

[@numistika]

@@danratsnapnames that would be a real revolution in communication!

[@danratsnapnames]

@@numistika not to mention computing. the speed that these things change at is unreal. the possibilities for faster clock rates are off the charts. problem is, we will likely crash our economy before we see it with inflation going the way it is.

[@numistika]

@@danratsnapnames we burn way too much fossil fuel for computing for fun. Just look at a problem with cryptocurrency that we have, how much energy it takes for mining it. We should fix the economy and develop eco friendly energy production, before continuing with energy hungry experiments. Anyways, we will hope for better future! )))

[@danratsnapnames]

@@numistika are you kidding me right now? are you serious? please dont talk like you know what your talking about when you DONT.. have you heard of SOLAR power crypto mining? and as for using fossil fuel for energy, wake the hell up, NOBODY IS BURING ANYTHING for ENERGY. your damn car you drive burns more fuel, and your damn electric car's have more plastic than anything else, that TAKES FOSSIL FUEL to make. power grids are powered by MANY MANY FORMS of energy. to make a statement like you did is IGNORENCE at its best.. sorry, but i dont think i even care what you think after that statement. CYA.

[@RicardoHernandez-nd5pp]

Ok...
