Eddy Currents and Magnetic Braking of a Pendulum Caused by Electromagnetic Induction 

Finally I got it....thank you so much sir... seriously we can understand physics practically more Thanks from INDIA

Sir, this is literally the best video explaining Eddy currents I have seen so far. Really appreciate that. Good work!

THIS SHOULD BE THE METHOD OF TEACHING NOT THAT THEORY, THANX SIR

Excellent! You completely cleared my concept of eddy currents.Thank you very much!

wow sir it was a concept clearing video..............love from INDIA...............

great work sir. i did this practical as a project for my senior year with some modifications of my own including a magnetized pendulum. i got the inspiration from your video. thanks again. appreciate your work and keep it up.

amazing. I though I know everything about simple experiments. This is like music to me I would listen while sleeping. What is amazing is how effective the braking is.

Excellent demonstration that acts like a bridge between the book and the mind.

Very very good explanation and very good way of explaining the concept. I cleared all my concepts of braking and the direction of current produced due to the eddy current. Many many thanks sir for clarifying my concept.

Very cool. Both electromagnetism courses I've taken in college so far seem to acknowledge Eddy currents, but not discuss them at all (probably because of their difficulty to calculate). Thanks for the clear demonstration.

Teaching method is super awesome 👏. I understood the concept thoroughly. Love from INDIA 🇮🇳 ✌️

You are truly wonderful. I never understood the topic in the Arabic language, so I turned to you and the explanation amazed me

I've been trying to understand this since the past 2 hrs and I finally did. Thank you.

Excellent sir Thank you for the nice video

Very clear thus too nice....

Thanks! Really needed it.. :)

merci ca repond a des question depuis des année , oui la meilleur

Thank you for this clear explanation!

Amazing video! I've understood the concept very well all thanks to you :)

Thank you Eng.tabarak.sahib

Exellent for explain.......Thank you..so much...you are No.1

Wow this finally made sense, and I can see I am not the only one. Thanks :)

Awesome video

Wow sir your explanation with specified experiment help me lot ,to understand the concept of eddy current. Thanks for your help.

thank u very much sir , from Iraq

tres belle demonstration ,bravo ca repond a mes question

Thank you, thank you, thank you.

nice video it' cleared my all doubts thank you sir,!!! 😊

Best video thanks

Thank you, sir, it was so confusing till I watched this video.

Underrated 👍

Very well explained!

Best best best Thanku so much 🥳🥳😜😜best explaination

That metal grinding sound.......unnerves me and my students 😂😂........ But otherwise thanks for an excellent demo

Nice

Great video. For clarification: when he says “opposing” magnets: it means opposite poles so the magnets are attracted to each other. Opposites attract. I made the mistake of placing the magnets so they repelled each other. That doesn’t create an Eddy Current.

well demonstrated... n well explained... wonder y this video has received only 50 likes... thnx a lot....

It's really good. .🔥.I know this concept very well Sir..

Really Nice demonstration! THANK YOU sir, !

Thank you eng.Hussain 💪💪

Sala this topic mere dimag me aa nahi raha tha.... thanks bro... understood very easily 😁

The red current loops are drawn incorrectly. Half of the loop must be outside the magnetic field. This is required so that the Lorentz force stops the pendulum (else the force on half of the current loop cancels the force on the other half). The current loops form around the boundary because they encircle the change of flux, which is at the boundary of the magnetic field.

Thank you very much best explanation

Awesome video.

Really interesting Loved it

Best explanation!

Thank you very much sir. You are really doing great...

Super👌

Very Helpful...thank u

#احمد_كتيب 💪💪💪

u r graet ...it clear all my doubts. .thanku

Thank You so much

Thank you sir very nicely explained!

Great explanation, though I'm wondering where in tarnation I can get those aluminium parts and the magnet ...

Well ,explained.

wow! Excelent !

اول عراقي طالب سادس تطبيقي مر من هنا 🤟

you are perfect. thank u so much for this

Helps alot

Thanks a lot sir! This helped me a lot :)

How does a battery operated magnetic pump work? There must be an aluminum showing between the coupled magnets, so how do they get around the Eddie current problem and keep their efficiency?

Thanks

Sir , I think you r wrong , what you r trying to say is that , electro magnetic damping happens due to change in magnetic field , well it's wrong . Let me explain , change in magnetic field produces induced electric filed.Change in magnetic flux or Eddy current causes electro magnetic damping . There is a difference .

And that is what we call visualisation. Our teachers explains us this on blackboard and we don't understand a thing.

Hello professor Melloch, My name is Rich and I was wondering if you could give me an opinion on a possible solution to a problem I’m having with a set of carburetors that would involve eddy current damping. The problem I’m having seems to be caused by the vacuum operated parts of the carbs lifting too early and fluttering. When this occurs, the engine quickly loses power and stalls, probably from an over rich condition. Here is a video of that happening; it should start at an appropriate time index. There is a white dot on the #3 throttle slide ( 3rd from the left), it bounces rapidly as the throttle is opened. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-VtmbGLGt3qw.html What I’m wondering is if I could put a small magnet(s) in the plastic throttle slide ears as a way to damp out the fluttering. Not sure what the carbs are made of - Aluminum or Zinc or some alloy in between. This video starts at a point showing the slide suspended in the carb body. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-6sd-YwEv0Jo.html I think the fluttering is caused by the air intake pulse on this 4 stroke engine and a lack of slide damping. I would appreciate your opinion as an expert in this field. Thanks

Thanks a lot...Sir😊

I don't understand anything you are saying, but it's pretty interesting.

Great Video. Well explained Just wanted to inquire whether there is a formula to calculate the magnetic damping caused by eddy's current.

I understand the direction that the magnetic field is induced but how does this lead to the pendulum stopping, i.e. how is a force created in he opposite direction to the motion?

If the eddy current results in a magnetic field that acts perpendicular to the motion of the pendulum, then why does it slow down? Wouldn't it need to experience a force in the opposite direction to the way its travelling in order for it to slow down? And does the magnetic field due to the eddy currents cancel out with the magnetic fields due to the bar magnets?

Could the effect be used as a drive coupler, would the torque be transferred effectively?

Can this demonstration equipment be purchased? My colleagues want one. Thanks 🙂

thank you!

Awesome application............

U r good sir

Please let me propose the following model to describe the pendulum position: for some positive constants {a, b}, the angle respect to the vertical x(t) should follow, in order of achieving a finite extinction time, something of the form: x''+ a sgn(x') sqrt(|x'|) [sqrt(2)/4 + |x'|^(3/2)] + b sin(x) = 0 hope you could try it matching the constants with experimental results, I am quite sure you aren't going to be dissapointed.

u r best

Wow !

Hi Michael!, I have a question... If there's a steady neodymium magnet and I horizontally slide an aluminum strip considerably close to it, the strip will slow down till it stops or it will just continue to slide but a bit slower?

sir what can we use as a non conducting material for this project instead of your third one?

اني طالب سادس اجبت اشوف النشاط

hey sir , i have lots of questions 1)can i use 10mm x 1mm neodymium magnet if not plz justify . 2) which type of sheet you have used steel or aluminium or stain less steel. 3)how you have attached the magnets at that object which you have used . 4)way you have attached the magnets in brief . plz justify beause i want to do it practically plz

Nice Presentation. Gives a thorough concept on eddy current braking. Can we use the same principle for generating torque? Please advise!

is it a neodymium magnet or just a regular magnet and where did you buy the aluminum like that )cuz of the shape of the aluminum(

So this can also generate a good amount of currrent

Why does braking occur? I can;t understand why the current generated leads to the braking ( or the dampening of the oscillations, if i may say ) ? I understood everything else in this video, just this fact. Please help.

This is so helpful. Thanks sir.. I have just one question. Can you explain once more why the eddy current can't flow in the third pendulum?

Thankuu sir

How could someone get these tools?

what is the stand you used to hold plates is there any other alternative

❣️

What is that rig called?

SD sir zindabad

Can I get pdf of this experiment For my investigation project

where did you get the pendulum from , website or shop

BESTTTTTTT !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I my humble opinion I feel the pendulum with slots would feel the induced reaction Eddy currents if the pendulum had wider bands with the open slots. It is because the band are so thin that Eddy currents cannot circulate. I maybe wrong. Would be grateful if someone knows and feel free to educate this simpleton.

can you please tell me the strength of the magnet used ,thickness of metal sheet and the amount of heat it produced

Is the kinetic energy from the paddle converted into thermal energy?
