Swarmalators: The five basic patterns
(Best viewed in 1.25x speed) Swarmalators intertwine two types of collective behavior observed in nature: swarming and synchronization. These two phenomena are typically regarded as being independent from each other. But what would actually happen if we linked, if we coupled the two phenomena? This is exactly what swarmalators do. Each swarmalator adjusts its clock based on the clock values and positions of other swarmalators. And it performs movements based on both the positions and clock values of other swarmalators.
This video explains the concept of swarmalators, discusses the five basic emergent patterns, and outlines applications in nature and technology.

Swarmalators combine two fundamental phenomena observed in nature: swarming and synchronization. This interplay gives rise to distinctive spatio-temporal patterns that emerge from the collective behavior of the individual entities.

Electricity from the Earth's magnetic field via electromagnetic induction
Переглядів 52316 годин тому
This experiment demonstrates the generation of electric current through electromagnetic induction using the Earth's magnetic field. A coil with copper wire with approximately windings is rotated. As the wire loops rotate within the Earth's magnetic field, the changing magnetic flux induces a current in the wire. This induced current is measured with a multimeter. Note that the "law of conservat...

Electromagnetic induction (Faraday's experiment)

Demonstration of electromagnetic induction discovered by Michael Faraday. An electric current in a wire coil generates a magnetic field, the change of which in turn generates an electric current in a wire loop. This "induced" current is measured.

Electromagnetic induction with a moving bar magnet
Переглядів 1,8 тис.2 роки тому
This experiment demonstrates electromagnetic induction with a moving bar magnet. When the bar magnet is brought near a solenoid (consisting of 1200 loops), an electric current is induced in the solenoid. This current is measured by an analog ampere meter. The induced current flows in such a direction that the magnetic field it creates is opposite to the magnetic field of the bar magnet (Lenz's ...

A moving magnet induces an electric current
Переглядів 3,7 тис.2 роки тому
This experiment illustrates the phenomenon of electromagnetic induction. If we move a bar magnet toward a solenoid (consisting of 1200 conducting loops), an electric current is inducted into the loops. If we hold the magnet still, no electric current will be induced (as there is no change in the magnetic flux). The faster we move the magnet the higher the induced current. (An additional video w...

Great video! Your explanation made it easy to follow. I thoroughly enjoyed it.
👍
The experiment demonstrated is great, but if you had plotted graphs between EMF and angular speed, along with other relevant variables, it would have provided more meaningful insights into understanding the interaction of Earth's magnetic field with the solenoid.But overall the explanation and the experiment was good🙂
I like bread
Very nice explanations, thank you!
❤❤❤😊😊😊😊pl🎉ease do another one for radiant energy, and power light led bulbs with rf Di pole antenna 🎉🎉
Let’s address the elephant in the room, what acts on earth as a power tool making us spin in an exact distance to the sun in a stable plane around the sun? It’s electromagnetism of cause, more exact Birkeland currents from the sun and cosmos -Strong current=Earthquake’s and volcanic activity=Global warming -Low current=Iceages
nicht wirklich gut gemacht. Warum ohne Ton, die Kamera direkt von oben wäre besser.
nice
why is she able to transmit 8mhz signal through an antenna less than 30m given that λ=cf will give us a wavelength of 38m approx??
Brilliant
Love it
Thanks!!
that's so slow💀😭🐢
Nice
It's like those tractors in the cars movie😂

So antenna is a pretty bad quality transfer also?
لطيف
❤❤❤❤❤❤❤❤❤❤
Keep it up sir.... You are doing an amazing job
You need energy to drive any drill machine. So energy remain same.
Sure! The law of conservation of energy holds. Here, electricity is converted to the mechanic rotation of the solenoid, which is in turn converted back to electricity. Energy is neither "created" or "destroyed", it is transformed from one form to another.
But you forgot to mention how much energy is going in vs how much you are getting out. 😅😅😂😂
Ty
Wtf
Radio signal send past and future possible
Die Induktion ist eher vom umgehenden metallischen Gegenständen enstanden und weniger vom Erdmagnetfeld.
Akka please speak in Tamil language please akka
when you get energy out without putting anything in give me a call.
And...what if I say, I have it? A motor generator that can charge LA batteries with the energy extracted from the local environment.
so have i from the air but that energy exists all day everyday you still getting it from the air it is free as you dont pay for it but your still putting in to get something out.@@tonyrebeiro
rare video that very close to how really antenna work...all the videos and google dont explain right how antenna work...explain it completly wrong.
Would be interesting to see this experiment conducted at different locations and different altitudes, including at low and high orbits.
Yes
Thank u so much❤ I was unable to understand this topic
ههههههه هذب بسبب الاحتكاك مع الفحم
And so, who provides the power for that drill??? 😅😂

@@bettstetter Your theory about conversion of energy, from one form to the other etc etc, is old stuff, taught in 'normal' engineering colleges. What you don't know is that this understanding is applicable ONLY to a 'Closed' system. It does not apply to an 'Open' system, as per Nikola Tesla. And.......all this has nothing to do with my primary question. I'm trying to point out that this experiment does not exhibit any useful phenomenon. We all know that the earth's magnetic field can be used in place of a local magnet, to generate a small amount of power in a rotating coil. If that coil is rotating from the energy, so generated, then it is something very very interesting. What you are showing is for school kids. Sorry. 😂🤣😅
"What you are showing is for school kids. Sorry. 😂🤣😅". I don't see anything wrong with teaching school kids (or, in this case, first-semester bachelor students) the well-known principle of electromagnetic induction.
@@bettstetter Thanks, Professor!! 🙏🙏
las botellas que tienen de base, influyen en el movimiento sincronizado? para mi si.-
Is copper electrode compulsory? We use copper ions to reduce but missing the importance of copper electrode
can you explain more in detail on how the antenna are connected to the function generator/oscilloscope? are each bar connected to negative and positive?
Right! And does the transmitting antenna contain some kind of RF power amplifier? Are the two antennas a special piece of lab equipment or just aluminum rods on a stand? This is a good video but a little more set-up information would make it great.
Was it uA or mA?
A missed opportunity to convey anything of import. In fact, a complete waste of two minutes for anyone who knows even the basic basics!
Klasse ! Aber was kann ich damit anfangen?? 🤔
how high can we get the frequencies?
Super 😊
pretty cool
wow excellent video to explain radio wave, thanks for sharing. Bravo .....
Are you moving the North pole or the South pole into the Solenoid?
it doesnt matter. it is the change in magnetic field that induces the current . the direction of the current is what zill change.
The realm is not a spinning ball. NASA is not a space agency.
Very interesting, do the other robots go to the one that signalled the cluster and deposit their items there?
Yes, the other robots go the cluster and pick up the items.
Great work! I am curious what will be possible in the master thesis 😁
I like it!
you helped a lot ❤
