*Magnetic monopoles do not exist but that has nothing to do with Faraday's Law* As far as the discussion about KVL and Fardaday's Law is concerned, please read the folowing if you want to get educated. In Dutch we say *"zachte heelmeesters, vuile wonden".* *I owe it to my multi million viewers to explain in detail why Electroboom is dead wrong.* *Many people make the same mistake that he made.* *All this is at the very roots of a correct understanding of Maxwell's eqs. I therefore have an obligation to set the record straight.* *This is my last msg.* Don't feel embarrassed if this physics is above your level; you are not alone. Non-conservative E-fields are not taught in high schools. I demonstrated at the end of my lecture #16 of my 8.02 E&M course at MIT that two identical voltmeters attached to the same 2 points in a circuit can show very different values. kzfaq.info://kzfaq.info/get/bejne/pK2BlaRjz93Ph30.html This can also be demonstrated with a transformer. kzfaq.info/get/bejne/mJ2ZZdh-3Z3LeKM.html *In fact, look more closely at my circuit; it is a transformer. My closed loop is the secondary winding (only 1 winding) of a transformer and the primary windings are in my electromagnet.* The reason is that an induced EMF (Faraday's Law) creates a non-conservative E field. This means that moving a test charge between the same 2 points in a circuit can require a different amount of energy (even with opposite signs!). You still aren't getting any energy for free, because it comes from the source of the time-varying magnetic field. When a voltmeter reads a value V it means that the integral of E dot dL across the voltmeter is V. In cases where Kirchhoff's loop rule (KVL) applies, 2 voltmeters attached to the same 2 points in a circuit will always show the same value. Kirchhoff's original text can be found in the following link, pages 497-514: books.google.de/books?id=Ig8t8yIz20UC. Clearly he was fully aware of the prerequisite for his "loop rule". KVL is a special case of Faraday's Law. That's why Faraday's Law is one of Maxwell's equations and KVL is not. My demo was first suggested and published by Romer in December 1982 in the American Journal of Physics. This demo has now become a classic; it's done all over the world at many colleges and universities. *ElectroBOOM and Dirk Van Meirvenne believe that 2 voltmeters attached to the same 2 points in a circuit must always show the same value which is not true.* It's quite embarrassing that they each posted a video on their channel in which they claim to have proof for their wrong ideas. Also read Professor John Belcher's thoughts on Faraday's Law and on KVL. Professor Belcher is my former colleague at MIT. freepdfhosting.com/0813df09f5.pdf *ElectroBOOM insulted me in his video by mentioning that the reason why my 2 voltmeters read different values was due to "bad probing". He stated that if I had done the demo correctly both voltmeters would have read the same value. He could not have been more wrong.* The following video may also help you to understand why 2 voltmeters attached to the same 2 points in a circuit can give very different readings. kzfaq.info/get/bejne/reCPetSAkrvWm2g.html

Ampère's Law is the magnetic equivalent of Gauss' Law. This can be derived from the Biot-Savart law (if you're interested in how). We'll create a path around the object we care about, and then integrate to determine the enclosed current.

Wow, thank you!

So nice of you

Sorunu anlamadım.

@@lecturesbywalterlewin.they9259hocam kusura bakmayın yanlış görmüşüm. Bu arada ben Türkiye’de bir lise öğrencisiyim. Yorumumu türkçe yanıtlamanız beni şaşırttı. Teşekkür ederim. Ve Tekrar özür dilerim.

Did you work out this problem though? (a) & (b) are easy but many make simple errors... (c) he said was easy, which it is if you have the knowledge, but that's only if you don't care about the "proof".

Hope u go to IIsc indian institute of science or IIST(under ISRO) rather than iit......my advice....iisc ranks better than iit

Even walter lewin knows.....iisc better

thank you for your very kind msg

many aricles have been publised about bursting pulsars. I suggest you read them first. If you then think you can still make a major contributing - submit your article to a refereed journal.
