*NOTES* *Electromagnetic Induction* - *Faraday's Discovery* : Passing an electric current through a conductor produces a magnetic field. Faraday explored the reverse idea, discovering that a change in the magnetic field around a conductor induces an electromotive force (e.m.f.), leading to the concept of electromagnetic induction. - *Experiment Setup* : Coil (solenoid) with a galvanometer, a magnet (NS) placed along the solenoid's axis. - *Observations* : 1. Stationary magnet (v=0): No galvanometer deflection. 2. Moving magnet toward solenoid: Right deflection (current B to A). 3. Stopped magnet: Galvanometer returns to zero. 4. Moving magnet away: Left deflection (current A to B). 5. Rapid oscillation: Increased galvanometer deflection. - *Faraday's Conclusions* : 1. Current flows only with relative motion between coil and magnet. 2. Reversal of magnet direction reverses current. 3. Faster motion induces more current. - *Explanation* : Changing magnetic flux linked with the coil induces an e.m.f., resulting in current flow when the circuit is closed. Faraday's laws state: 1. Any change in magnetic flux induces e.m.f. 2. Magnitude of induced e.m.f. is proportional to the rate of change of magnetic flux. - *Factors Affecting Induced e.m.f.* : - Depends on the rate of change of magnetic flux per coil turn and the number of turns. - *Direction of Induced e.m.f.* : - *Lenz's Law* : Induced e.m.f. opposes the cause producing it. Current direction is such that it hinders the change in magnetic flux. - *Fleming's Right Hand Rule* : Thumb (motion), forefinger (magnetic field), and central finger (induced current) directions. *_Note: Electromagnetic induction is a foundational principle for devices like transformers, illustrating the conversion of mechanical energy to electrical energy._*
Yes, emf is induced. According to Faraday's law of electromagnetic induction there should be change in Magnetic flux linked with the coil, so as to induce emf. The thing to note is that the emf lasts as long as the Magnetic flux changes. Say you decrease the flux and further you don't increase it, there will be no emf. Hope this helps.
You are great sir!!!!!! I searched many vedios on the yt to understand this topic but I was not able to understand it but this vedio cleared all my doubts. Thank you sir thank you very much
thank you so much sir ur teaching skills are very amazing 🤩🤩i have been studying from ur videos from past 2 years and it has really helped me in physics ❤...
By using - Use Lenz's Law: Induced current opposes the change in magnetic flux. - Use Fleming's Right Hand Rule: Thumb (motion), forefinger (magnetic field), and central finger (induced current) should be mutually perpendicular. *Remember, both methods give the same result: the direction of the induced current opposing the change in magnetic flux.*
Transformer mein current change karne ke liye electromagnetic induction ka concept istemal hota hai. Transformer mein do coils hoti hain - primary coil aur secondary coil. Jab primary coil mein current flow hota hai, magnetic field create hoti hai. Yeh magnetic field secondary coil ke saath share hoti hai. Jab magnetic field mein changes hote hain (jaise current ko badla jata hai), toh secondary coil mein electromotive force (EMF) induce hota hai. Is induced EMF ke karan, secondary coil mein current flow hota hai. Transformer ke design mein primary aur secondary coil ke turns ka ratio determine karta hai ki current kaise change hoga. Agar secondary coil ke turns zyada hain, toh output current primary current ke muqablay mein zyada hota hai (step-up transformer). Aur agar secondary coil ke turns kam hain, toh output current primary current ke muqablay mein kam hota hai (step-down transformer). Is tarah se transformer electromagnetic induction ka principle istemal karke current ko change karta hai.
Bruhhh!! We have to use right hand thumb rule here not the left one and even left hand thumb rule is not even applicable here.... It have completely different concept. Try with ur right hand!!
I've searched many yt teachers but never understood what they taught, you are the only exception sir. Thank you so much for explaining this.
I don't even remeber that my teacher taught all these in ur class........ sir your classes are very understandable .....thnku......🙏😊
Best physics teacher!!!!
Kya shi explain kia h sir apne iss vdo m electromagnetic induction ko👍👍
Mzza aa gya smjh k aur jsa apne suru m bola tha scch m ab koi doubt nhi rh gya iss topic m
Just a masterpiece!
You are a dream teacher..
Sir, please upload more and more videos, it will benefit us greatly.

Wonderful sirrrrrrrr really amazing explanation.. your teaching is mindblowing.. all my doubts gets clear by your marvelous videos ❤ Thank u
Sir ji chaaaa gyeeee
tussii great ho paaji✍💪
Sir thank you so much for your videos, they are helping me a lot with my boards. Lots of love to you.
You are welcome
After wasting few months on another youtube videos, I found the best video today which cleared my this 36:16 doubt. Thank you too much Sir
I lack words to appreciate you enough! Thanks a lot sir!
Thank you so much sir!!! My whole doubt is clear now
Kyaa bhadiyaa hi samjhate ho yaarr aapp... Systummm baaandd diyaaa
Sir i am literally giving you a standing ovation 🙏🙏🙏🙏 Thank you may God give you immense of happiness and wealthhhhh ❤🎉
Sir sab smjh me aagya aur koi aap ki tarah nahi smjha pata ❤
Best explanation sir and very detail concept ❤❤ understand thank you so much sir ❤❤❤
Mazza aa gaya sir patta hi nhi lagga ke kbb time nikkal gaya
Sir aapka fav. Topic =mera fav. Topic ❤❤❤
Is topic main hi kuch baat hai ..

Huge respect😭❤️thank youuu soo much for your efforts sir✨❤️
Sir if magnetic flux is decreasing then is there emf is induced or not?? Please clear my doubt

Sir plz do previous year question too plz before 9th of jan due to pre boards sir plz it's my humble request..
I will try
best explanation! understood everything
Sir you deserve it 👏👏👏👏👏👏👏👏
sir please teach use of electromagnet in a electric bell and simple d.c. motor
Ok
@@RANAACADEMYsir please use the book of dalala chemistry class 10 not Selina.
Legendary teacher
Thank you
Superb explanation sir 😌
Last time I got 50 out of 48 only because of you and I hope tom.. is my 2 semester and I hope so now too.. you are best teacher ❤️💕
50 out of 48!?!?!? man u are a bozo frrrrr 💀💀💀

Mind-blowing sir 😀😀😀✨✨
Amazing explanation sir😊 thanks
Excellent teacher in my life 🧬
Thank you
Awesome explanation. Thanks a lot sir 😊
You explain very nicely sir❤
Marvellous explaining
Sir but how do we know that current is flowing from A to B in first experiment how to determine direction of current 05:42
In the first experiment the current is flowing from B to A and is determined by galvanometer.
❤💯💯 thank u sir
Sir .. Dc motor ka lecture nhi h.. sir plz post it... We have it in our syllabus this yr
Kamaal hai
Thank you
Sir from now this concept becomes favourite of mine also.
Sir u are great ❤
Sir thanks for explaining for deep
Sir how will we know in which direction galvanometer will deflect ?
learn it
By using
- Use Lenz's Law: Induced current opposes the change in magnetic flux.
- Use Fleming's Right Hand Rule: Thumb (motion), forefinger (magnetic field), and central finger (induced current) should be mutually perpendicular.
*Remember, both methods give the same result: the direction of the induced current opposing the change in magnetic flux.*
Amazing video sir
nice explanation ❤
Glad you liked it
Thank you Sir 🙏
Great 👍 sir
Tyy

thank you so muccccch

Induced emf kya hota hai sir
that emf which is produced due to the change in the magnetic flux in the coil

Sir you have left electromagnetic bell and dc motor topic plz explain them too
I think Dc is not our syllabus
💯💯
Good teacher

Thank u sir
Sir plz make video on dc motor application plzz sir
emf kya hota hai?Hindi mei pls

Do dr viraf icse chemistry 10th icse plssssssssssssssssss
Ok
@@RANAACADEMY thank you sooo much sir
if we use left hand thumb rule then the direction of current in coming downward 👇!!!!
Bruhhh!! We have to use right hand thumb rule here not the left one and even left hand thumb rule is not even applicable here.... It have completely different concept.
