left hand rule for motors and right hand rule for generators

very good explanation!

Why did you divide by cos theta?

4:04 why is that?

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.

Thank you for your beautiful explanations. How is it that Kepler was correct in his calculations despite his belief 18:39 that the earth is the centre of the planetary system when the sun is. Ramzi

I never understood why Maxwell did not receive the Copley Medal.

thankyou this really helped me understand the difference between right hand grip for solenoids and general wires

Planck's approach was to analyze the entropy of blackbody radiation as a function of energy. To make both high-frequency and low-frequency data consistent with the Second Law of Thermodynamics, he included an additional "guess" term proportional to the frequency (hf); this results in Planck's Law. Planck's application of Boltzmann's Statistical Mechanics to justify his guess then led to his revolutionary conclusion that the material of the walls emit and absorb radiation in discrete quanta. A paper titled "Planck’s Route to the Black Body Radiation Formula and Quantization" by Michael Fowler (7/25/08) gives a nice discussion.

Fact: over a 15-year period (of 5495 days) Mars returns facing a given star in this curious sequence of time intervals: 707 + 707 + 707 +707 + 707 +707+ 707 + 546 days. As expounded and illustrated in Chapter 5 of my new TYCHOS book (2nd Edition / Dec 2023), this means that the geoheliocentric model devised by Tycho Brahe is the only possible configuration of our Solar System. This, because the 'odd behavior' of Mars - what with its "short Empiric Sidereal Interval" of only 546 days is - perfectly accounted for in Brahe's model. It is now high time to realize this undeniable fact - and to expose Kepler's fraudulent ways in his vain quest to validate heliocentrism (as already discovered and denounced by Prof. W.H. Donahue - the American translator of Kepler's "Astronomia Nova" - back in 1988).

Couldn't explain in a very simple way,,,you even didn't say what Lenz law about and why we need it ?

does the direction of the field lines be perpendicular to the loop for this to work? only because they used a parallel notifier with the B(magnetic field strength).

how do we dare feign to accurately assign colors to wavelengths within the "visible spectrum" we can't directly perceive??? 10:20 is there some inference or extrapolation or Fourier transform of sorts to prove our assignment is remotely correct? is it proven by wave interference theory?

5:59 gross concept error: our eyes are limited to activation by only three different wavelength intensities, i.e. red, blue, and green. the "visible" spectrum is just a trick, and we don't actually know which color corresponds to various wavelengths. we painted a false picture on a black and white mystery, until chemical sensors, aka photographic film, was made. even then, the colored rays corresponding to pure orange, yellow, purple, etc. will only appear as grey tones on the film.

This is fortunately going to help me for my physics exam tomorrow. Thank you

Bravo bro!

For q17, you can alternatively find it with the right hand palm rule. Since the conductor has current in QR, with right hand grip rule, magnetic field lines are directed to the right above QR. As the cathode ray move into the page, then it is experiencing a force upwards due to right hand palm rule. (Note that electron is opposite to positive charge) As resistance increases, force decreases and thus moves toward Z.

can you please provide links to the information about the formulas for thermodynamic energy conversion that takes place and how to effect a concentrated released of ionized gas energy to simulate a blast thanks

great presentation!

You guys are producing the best on this content. So much info in one short KZfaq clip.

It is not clear why introducing a quantized constant solves the 'catastrophe'. Thats the video I want to see! Thank you.

wonderful explanation despite funny pronunciations to mine americanized wernicke's area.

Nice presentation. However, it is "damp" not "dampen." It is "damper" not "dampener." Thanks!

amazing, gonna use this for my a level physics exam tomorrow. thanks

Very good Sir! My name is Fernando

@14:20, shouldn't the orange time be greater than the yellow time? Because yellow moves in the same direction as the ether.

since the metals dees have an opening (otherwise how would the protons enter?), doesn't that mean electric field can be inside the dees? metals will block electric fields if they are a closed surface but here the metal dees are open

I have a question about converting Vsource *time /λ to Vsource / Vwave, as the time might not equal the time taken for the wave to move for 1 period, so can it be converted?

That was amazing!

Antigravity

Thank you for such an insightful and beautiful video

i am doing my presentation on plasma and that helped a lot

Tony Iommi 0:49 - Jeff Daniels 8:03 - Gene Hackman 8:11

Thanks a lot!

This is actually really helpful

Wouldnt it escape perpendicular to the tangent, and not tangentially?

The gel pack is genius

They are emited in opposite directions not because of conservation of energy but of momentum! It is mentioned twice wrongly in the video.

guys will it work if use a metal plate instead of a heat sink??

great for A-Level physics (UK physics exam) thanks!!!!

simple....Black Walls....6 of em....and there Ultra energetic !!

Best video

Interesting !

Job well done ❤️

Why S=vt and S= Ut+1/2 at2 dont get same distance when acceleration 9.8

Hello sir In the alpha decay of uranium 238 the newly formed element is also short by 2 electrons. Where do these electrons go in the process? Regards M Jafar

I love this content! I can see how Faraday's and Lenz's laws work clearly here! Thank you so much for the explanation and demonstration.

Excellent thank you, just at the level I can understand. Best Ive seen
