Good Illustration Sir, Could you please provide the illustrations for these four physical quantities Magnetic Field Intensity and Magnetic Flux Density Electric Field Intensity and Electric Flux Density
You need to put safety warnings in the video, not in the blub- many people don't read the blurb. Especially important given how dangerous creating lichtenburg figures in wood is- people have been seriously injured doing it.
how did they amanage to freeze it so lowe..Lne is minus 196 c
I wonder if candy would sink
4 years late but this video is short, clear, concise, and gives a great demonstration and visualization of how dielectric breakdown acts in air (hence why when transformers do this the electric arc also rises until the breaking point which I did not understand until you just mentioned about the hot air rising which helped me visualize the whole thing)
Thank you Master for the great courses but can we say that all the motors today of the electric appliances are designed only with Barlows wheel design without any development?🇱🇧❤️💎🌹🌷
I wish to know 2 things : 1 will the condensate liquid helium be contained by allotropes like graphene and fullerenes, 2 : what if any is the thermal effect on said liquid helium when exposed to a high tesla magnetic filed . Asking for a friend

4:50 when quater wave plate is placed in between, it gives circular wave, and when analyser is rotated, it gives same intensity.
ruined by a mask. cool vid, though.
He doesn't reveal or discuss that he had to pull that Gd away in the first test because it still had remnant ferromag properties even above Curie point. it just cant hold up the dense wgt after long time relaxing of ferromag crystal field.
what is that plate which u touch the plate of capacitor?
Always puzzled!
The feather clearly beat the penny.
This is hard to understand. Either photons have mass or they don't. My understanding is they don't. Therefore, how can momentum be imparted if mass equals zero? Also there is a second variable related to black body or thermal heating? 😕
The idea that mass is necessary for momentum comes from classical mechanics. Special relativity tells us that photons actually do have momentum even with no mass. A Crooke's radiometer is meant to be an analog for that, but it works using an unrelated physical mechanism, where light is used to heat things up, as explained in the video.
@@Tobincorporated-z Ha, tricky. Thanks for the clarification.

Very helpful. Cleared my concepts just days before my IAL Physics exam. Thank you very much!!
NIce Demo - but raises the question of what is really happening to the electric Channel on the baking Soda Demo and why it behaves in that pattern...SCIENCE!
Rocket lift off magnesium thunderstorm?
I have solved Faraday's Paradox and would like your opinion...ua-cam.com/video/Kl0-sKbZsKM/v-deo.html
great demonstration
Man!! This is so cool. 😍
Noice.
This has to be the coolest thing i have seen this month, and now that I’ve seen this, i have the irresistible urge to try this at home.
What Movie Soundtracks have acquired this Sound Effect ¿°♡°?
Maxwell 4 equation time varying magnetic field
If we had to, how would we write an expression for the pressure at the bottom point (arch) of the tube?
the slight of Hand and flipping the magnet....magic...diverting attention
sir kindly let me know that what does thickness of the plates has any effect on amount of capacitance. if we have two capacitors of same area A of each plate of thickness 3 mm in 2nd capacitor of same area A of each plate but thickness of each plate is 10 mm. is this condition results in increase of capacitance?
Don't you think this is a question of a right combination of the momentum in x direction and y? I mean, as the bullet is lighter, or the x initial speed is faster, it will reach the monkey y axis is a faster time, if the y initial speed is faster, the vertex is the parabola could be further than the original point of monkey. So what is the point?
These phenomena always intrigued me in my physics classes.
Do the One Dr. Feynman did with radio waves as the wave length was long enough to appreciate the changes. I gave away my disk to a budding physicist ( I hope). A stern gurlach apparatus with differing tone resulting from one or two slits being open.
At time 0.22, perhaps you meant to say, "voltage", or "electric field", or "EMF", rather than "magnetic field"? Nice demo!

Deep. Incredible. Thanks
Please explain why you are using the right hand rule for a motor. I’m under the impression it’s left hand for motors and right hand for generators
gold can be created by stars and the matter compiler ... or fusion process
nice equipment, hope to see how DC does too during the moment of charging
Excellent demonstration, Very well constructed machine, let alone the fact that the humidity conditions were excellent too!
Excellent experiment guys. Super.
This same force makes it impossible to brake and turn simultaneously on a motorcycle (which nearly cost me my life).
My brother in Christ, trail braking necessitates you have brake pressure while turning
The primary reason that motorcycles lean in turns is due to the tires being steered outwards from under the bike+rider, leaning the bike+rider inwards. The precession related effect during the initial counter-steering accounts for only about 10% of the roll torque that leans the bike. The issue with braking while turning is that the front tire's contact patch is offset to the inside, and braking will tend to further steer the front wheel inwards, and the rider has to oppose this with some opposing outwards counter-steering torque. Most motorcycles tend to straighten up when leaned, and a rider has to exert some outwards counter-steering torque to steer less inwards in order to hold a steady lean angle. While leaned, counter-steering still applies, steer inwards more to lean less, steer inwards less to lean more. For a rider used to counter-steering, braking in a turn will not be an issue, since the normal counter-steering reaction will allow a rider to hold the current lean angle steady while braking (the rider will also to reduce counter-steering torque when the rider stops applying the front brake).
Excellent visual!
Can U make another one to show what happens when U (try to) turn a gyro/wheel, sideways, and what happens when U turn a fully gimbaled gyro thru full 360 degrees. I think U would need to color the gimbal halves and gyro sides differently and be able to show in which direction the gyro is spinning.
What do U mean by "If I try to spin it around this axis, I can raise or lower it"? If U are turning the vertical shaft, then why isn't the gyro precessing/turning? Why don't U show us what happens when U push the back end, of it, sideways.
What a great video tysm for this.
awsome awsome
What fascinates me as much as the experiment itself are the methods used to achieve such a state. After the explanation at the beginning, while still no small feat, it was surprisingly simple. Basically layers of transparent insulators mixed with pressure reduction, when all is said and done. (Read More). I'm fascinated that one can literally achieve a temperature close to 0 K with a device smaller than a barrel while standing a few feet away at room temperature.
Interesting + and- signs were used for north and south poles.
That transfer line -- did you warn the NMR team before you borrowed it? :P
Cool 😎🤠
