- Mutual Induction
Make a coil with insulated conducting copper wire at one end of a soft iron core and connect its ends to a torch cell through a switch Make another coil at the other end of the same soft iron core and Connects the ends of the coil into a galvanometer. Of these, the circuit which is connected to the battery is called primary circuit and that connected to the galvanometer is called secondary circuit. Here, there is no interconnection between primary and secondary connections.
When we switch on, the galvanometer deflects to one side and returns back to its mean position. When we switch off, the galvanometer deflects to opposite direction and come back to original position.
Now repeat the experiment connecting a 6V AC supply instead of the DC in the primary coil and 6V bulb instead of the galvanometer in the secondary, the bulb starts glowing continuously. How does it happen?
When ac passes through a solenoid, a fluctuating magnetic field is produced around it.
When the strength of the current in one of the two adjacent coil changes, a change take place in the magnetic field around. As a result of this, an emf is induced in the second coil. This phenomenon is mutual induction.
The emf produced due to mutual induction and the number of turns in the coil are inter related .If we increase the number of coils in the secondary, the intensity of the bulb also will increase. If we cut down the number of turns into half, the intensity of the glow also decreases. From this, we can conclude that there is a relation between the emf produced by mutual induction and number of turns.
🤣🤣 background music is like something is very thriller and suspense in this topic 😂😂
hhhhhh😂
@@fawadalam7005 Like an episode of dexter
True man 😢😢😢
i thought about the same and about to comment....
Oh yeah 😅 Like how mysterious can that mutual inductance become ? Creepy & suspenseful music 🎵😂😂🤣
Uff.. theey... backgroud music😂⚡️
I felt like I was watching a investigation story 😂
Oh thanks for 1 like, the most I have got
😂😂😂
😂
I think I'm watching a video class or a horror movie🤣
Background music is just annoying
Feeling like a horror movie
Ha naaa
You should annoy the mutual induction dude
Physics is horror tho
Snake master background...
Andhass at its peak ✨️🤌🏻
Kidilaam da monee
The background music is freaking me out and my mind is like: ooo the galvanometre is moved by a ghost😅😂😂😂😂
Couldn't you use some good background music? That music irritates and can't watch your class politely 😕
Very good 🎉🎉 very beatiful explanation i will understand this vedio what is mutual induction 💯💯💯💯💯💯💯💯💯💯🔥🔥🔥🔥🔥🔥🔥🔥💯 thankyou sirrrrrr 💚💚💚
Polikk❤
🤣
Poli.... Plz upload other topics also👌
Yaya
Ngl oralallee.... Oree dp

Malayali 😂
Excellent explaination
Superb**
Super 😍👍
Eth ena investigation ano😅
I thought I was going to disappear after I watched this, music had me gassed
Amazing
I understand thanks
Thanks Sir
oho
Baground music is a phsyco story
محمود مجدي 👆🏼
احيه هو انا بس اللي جاي من عند مستر محمود مجدي ولا اي؟ 😂😂
لا معاك يصاحبى
متخافش يعم كلنا جينا😂😂
scarey musicccccc😂
Bgm is too disturbing
Plss upload Electromagnet explanation
Dude... Really my guy? That's self explainatory if u ask me
dramatic
The music from mobile game zwarfare
Concentrate on topic instead of background music
Background sound
This music made me afraid more than lam 😂
Onnu poda😁
