Maxwell’s Equations Part 3: Faraday’s Law

[@TheMemesofDestruction]

Love it! Thank you Professor! ^.^

[@igorab1]

Emil Lenz[1][2] or Heinrich Lenz in some countries, was a Russian physicist who is most noted for formulating Lenz's law in electrodynamics in 1834.[3]

Hi. Dave. I wanted to correct the typo in the integral form of Faraday's law, the closed path (line) integral only needs one integral on the left side of the integral form.

[@briandwi2504]

Great,thanks. I thought something was wrong there.

[@MohammadAlshahrani]

in 4:12 the charges in the coil suppose to be + or -?

[@rachidlamzougui1683]

Thanks Dave 🎉

[@rickkwitkoski1976]

THIS stuff, is what scared me away from physics. I only did what I needed to do for my undergrad... Thanks, Dave. But I will need to watch these again.

[@dheeraj3945]

Great video as always. At 2:17 I finally understood why Wikipedia sucks at math, it seems really hard to put calculus into words 😂 Since Faraday's laws are dynamic in nature, using aminated graphics all throughout the video to illustrate individual concepts would've made it much easier to grasp. Thanks for the video

[@berserk.958]

Continue to do more videos on physics sir

[@rossfriedman6570]

What's the differece between magnetic flux and amps?

[@pramodsingh7898]

Thanks

[@rossfriedman6570]

I don't understand why momentum is measured in watts but angular momentum "spin" is measured in joule seconds

[@rossfriedman6570]

What's the difference between electromotive force and volts?

[@lilliaplayer9439]

Volt is the measuring unit, electromotive force is the magnitude, and is usually a synonym for voltage.

[@sideeggunnecessary]

Im just gonna listen and not learn anything then in 2 weeks take a test

[@CoderSV3]

Feeling this HARD rn and the test is Tuesday

[@imserious5994]

How did your test go😅

[@sideeggunnecessary]

@@imserious5994 got an A+ apparently I'm a sponge for knowledge

[@gwizafinance]

You are the best

[@rossfriedman6570]

What does "flux" mean in "magnetic flux"?

[@rachidlamzougui1683]

Flux refers to the total amount of magnetic field passing through a given area, it is how much of the magnetic field interacting with that area. It may be at its maximum or zero

[@Kage1128]

when are we getting a statistics course ;)

"Water, fire, air and dirt... F*cking magnets, how do they work?"🤔

[@achyuththouta6957]

This is good

[@apertureonline9566]

I think gravity is the interference pattern between both of these forces, where the exact composition using M theory can not be calculated.

[@apertureonline9566]

I also think that static electricity is why galaxies are stable geometrically. I think Zeta Reticuli would basically float off into space and static electricity is holding it together. I did math but idk like that it would be true. I used triangles, so it was some trigonometry.

[@Sanni_Abacha]

Wetin you dy talk guy😭😂

[@waelfadlallah8939]

I didn't really understand but thank god for Germans :)

[@StarsManny]

Germans?

[@Xavus-137]

There only a week left before my high school and I tried put anything in there and got nothing, really disappointed in my ability to learn.

[@captainchazz42]

If you're still monitoring these comments, Mr. Professor, please do a refresher on the heliocentric vs the geocentric models of planetary orbits. There seems to be somr misinformation gaining traction amongst the tin foil hats against the heliocentric model ysing Tychos' theory. Thanks.

[@ProfessorDaveExplains]

I explain it thoroughly in my astronomy series.

[@bharatshah7271]

First?

[@michaellamoreaux4402]

I have discovered that Faraday's law of induction is unintentional disinformation. In the case of a static magnetic field, if a circuit linked by the field expands, thereby increasing the flux linking the circuit, Faraday's law states that the changing flux produces an emf in the circuit. This is false; the changing flux linkage has no effect. There is an emf in the circuit of the same value as predicted by Faraday's law. It is motional emf due to the motion of the conductor of the circuit through the magntic field. Thus, Faraday's law is false. There are also exceptions to Faraday's law, as pointed out in The Feynman Lectures on Physics. Faraday's law is just math, not physics. It is a case of correlation, not causation. Faraday's law encompasses the Maxwell-Faraday law, which is one of Maxwell's equations. That part is true. That is why Faraday's law is like disinformation. It is partially true and partially false.

[@brianbanks3044]

hmmm magnetic flux...sounds like a Flat Earther's bullet point

[@o_o-lj1ym]

I doubt a flat earther would know or understand what flux is

I like how you simplify things, so that the complicated becomes uncomplicated, and quite fun, actually. Have you ever seen, "The Microworld with Dr. Shoemaker"? kzbin.info/www/bejne/noKupWqEbsqHr6M
