Lenz's Law | Magnetic forces, magnetic fields, and Faraday's law | Physics | Khan Academy

Lenz's Law - seeing that the magnetic field induced by a current induced by a change in magnetic flux (Faraday's Law) counteracts the change in flux.

Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

For free. For everyone. Forever. #YouCanLearnAnything

I am very impressed by the right hands that you drew.

"Let me find a nice color for the current". Love you Sal.

[PerrinTan]

Perfect voice, perfect drawings, perfect colours, PERFECT EXPLANATION

[WfrArcPol]

4 teachers/lecturers explained this to me and I didn't get it. This video makes me finally understand the law. Why am I even paying for uni

[christiangutierrez]

when you come to Khan academy wanting to learn physics and get an art lesson in the process

You are a Legend, What my teacher couldn't teach me in 2 months, you taught me in 6 minutes.
Keep up the awesome work.

This was such an amazing video! First time here, but I understood with an unexpected ease since Physics is my Achilles’ Heel. Thank you so much sir 😊🇮🇳

[mlc]

I've been stuck trying to understand this law for a couple days now. I didn't know that a 6 minute video could make me finally understand it. Thank you!!!

(Also the hand drawings are pretty good!)

[AmandaMagana]

thank you!!!
-UCLA student with physics final in two days and still doesn't understand lenz's law

[Amrdestroyer]

Cool, please keep on making physics videos' sir! After you finish electromagnetism, could you please start to explain quantum mechanics? Please?

[faroteur]

pays $$$ for college. comes to youtube to learn for free.

[kajalk]

How could he have so deep understanding of almost all disciplines? Huge respect and love.

[EmpyreanLightASMR]

I think I want to add that for some reason "the conservation of energy" (which is mentioned at 5:00) isn't said by teachers when teaching this concept. It took multiple youtube videos before I finally heard that phrase, and I figured it was the case, but still. It helps to know *why* Lenz's law is working. I'm sure the textbook says it, but those things are written by out-of-touch people.

[SaiAbitathaDUCIC]

I wish the law of conservation of energy could be violated somehow

[stargazezz]

It's taking me a yearrr to understand this concept...
Idk how I will do on my physics exam tomorrow 😥



And this actually helps me understand the basic concepts
Thank you :)🙏

[gurushajuneja]

Infinity loop of increasing energy 😂😂dude nice explanation . Thanks a lot sal . It does a lot for students like us

[hassanmehedi]

This is a very clear lesson. I just loved it.

[Stella-hxrn]

I've been coming back to this video so many times! No one has explained Lenz's law better. Thank you so much!

[rrennnerr]

These videos will be clutch later this year during my first year of college.

Khan academy you always give me something much better than my expectations THANK YOU 😌 ☺ KEEP GOING 👍👍
