Thank you I tried it and it worked ...few things not mentioned here transistor has specific points that need to be connected correctly or it will not work.

[@knowledgecycle]

What???....... that's not correct actually, You can connect anywhere to those pins.....there is no any specific point Btw thanks for giving your feedback that model is working fine 👍

[@krishnaverma3635]

I have successfully made this thank you First things is used soldering iron to join the connection otherwise it will not work and other thing is I use 1.5 k ohm resistance and it started working properly

[@knowledgecycle]

If your model is not working read the following instructions: ◾Use 2N2222A transistor with 27K resistor insted of 547B or BC547 ◾After testing the model disconnect the battery with coil to prevent the battery from discharge ◾Be careful with the connection of transistor- Many people did the wrong connection, they confused in connection of first and last pin of transistor ◾Use only Red or Green LED because the golw very well on low power supply...... avoid using white light ◾Remove the insulation of that part of wire that is to be connected to other components ◾In some situation the shopkeeper give you the wrong value of resistance and due to the lack of knowledge about the colour code many students bring it at home and use in the project To verify any other resistance value just visit on this website- www.calculator.net/resistor-calculator.html Note: connection for both transistor is not same the connection shown in the video is for BC547 transistor if you are using 2N2222A transistor there is small difference in connection......do do the connection as shown in circuit diagram 👇👇 🔆 Circuit diagram for 2N2222A transistor: drive.google.com/file/d/1WV5XMhyOnos-5geqnNve6LFU_7zeUcCD/view?usp=drivesdk Edit date: 02/04/2022

@@thakursahilsingh5578 bhai lagta apke concept weak h EMI ke, jabtak magnetic flux mein change ayega matlab current dhire dhire badhega jabtak full na hojaye. Full flow of current ke thodi der baad led band hojayega kyuki magnetic flux mein change ruk gya. You can use a switch in between and turn it off and on again.

The whole science behind this is Battery SE current flow ho raha hai, aur resister aur inductor SE current induced ho raha hai jiske wajh se MF ban raha hai Jo ki dusri coil pr uska jb impact ho raha hai toh batti jal rahi hai..

[@AnkanDronzerMondal]

For induced EMF you need the flux to change But here he uses DC current so the magnetic field remains same EMI only works with AC Either you need to change the Area or the magnetic field to get Induced EMF EMF = dφ/dt here the flux is same so idk how EMF is getting induced

Arey Wo AC circuit ban gya aur usmein flux ki direction change ho rhi

Battery directly connected to coil also produce magnetic field Then why we need those components like resistor and transistor? Answer is Just to make a alternating (continuously changing) magnetic field Hope you understand the concept

Bhai C1815Y wala transistor aur 22k ka resister kaam karega isme plzz reply

[@knowledgecycle]

No......you can use only 547B or BC547 or 2N2222A transistor

Bhaia mai class 12 ka hu, maine ye timepass ke lie 10th mai bnaya tha ab emi ka chapter hai to lga ki iska principle emi pe based hai, lekin mai agar coil ko move na bhi kru tb bhi led glow kr rhi h to iska principle thoda sa btado pls

[@knowledgecycle]

The resistor, inductor, and transistor make as an oscillator circuit. Oscillator converts a DC to AC. As an AC is passed through the coil, an alternating magnetic field gets created. The alternating magnetic field induces and AC in the secondary coil (just like a transformer). The LED is connected blinks, it blinks so fast and seems like it is glowing continuously

First I try using 547B transistor it was not working but when I tried using 2N2222A transistor with 15k resistor it was working how? Thank you for this project ❤️

[@knowledgecycle]

May be that transistor was defective.......because in video I have use the same 547B and 15k resistor

[@chiraggaming2577]

May be . Thank you for replying

[@Instaupdates07]

@@knowledgecycle mine 547B is also not working so should I try 2N2222A with 15k resister ?

[@knowledgecycle]

According to this comment you should try it.......if it still not works you don't worry just DM me on instagram I will try to sort it out

[@ishikajaiswal2517]

Can we use two led connected to each other in place of one???

[@riyamishra6003]

Thanks sir for this helpful video👍

[@akankshanaugain6181]

Sir can I use KTN2222 resistor?? Is it same like 2N2222A transistor
