Don't use ppt, use your handwritten notes which is better and easy understandable
Same need
Sir i think we understand better when you use pen and paper
you have explained partially incorrect. There is a fixed magnetic field provided to magnetron. And the bunching takes place because when oscillations happen in anode cavity, then a tangential elec field component is generated by RF; which in turn retards the electrons. Moreover, the oscillations happen not because of LC circuit . Its because when RF is applied to the cavity, the cavity behaves as short circuited Transmission line of different wavelengths (as per the no of cavities in design). Thus a resonance occurs due to standing waves generated.
✌👏Excellent explanation.Thankyou sir
Sir please make a video on hull cut off equation for cylindrical magnetron and Hartree voltage equation for magnetron.
Tq so much sir , keep making more videos
Thanks for uploading :)
awesome teaching i undestood properly thanks for video ,this 1 video cleared all my doubts thank u
Nice explanation about magnetron
Excellent explanation. Thanks
Your welcome
Love this! can it be used to generate other waves? not just microwaves...?
It gives out rf signal, hence only rf output
Super sir .it is easy to follow your teaching.
Your positive comments motivates me.
Teachers like me just wants positive comment from student.
Love from you guys means a lot to me.
My goal is to create largest community of engineers in entire globe. Please help me by sharing this playlist with your friends.
Thank u so much
Sir please give us some theory part of this. The points you explain please give us in pdf.
Super explinaion sir
nice explanation
Does the shape of the cavity change the output?
nice sir
Here you said that when magnetic field is increased less no. of electron moves from cathode to anode so how velocity increase with increase in magnetic force
Thank you 🤩🤩
Your welcome 🙏
God bless you 🙏
Thanks
Thanks sir
it would be better if u could decrease the length of the videos. by the way, great works
Thankyou nice videos😎
Your welcome 🙏
Dear sir ,
I want to know from where we are taking output
Hello,
I have a question, can the electro magnetic waves be diverted in a pipe ? In case if i have 4 compartments to be cooked, I have one centralized Magnetron, Can I divert the waves through any tube like structure ? Is it possible to have a solenoids control 4 valves for each compartment and turn on in each compartment when ever required.
And in a normal microwave oven, How is the distance influenced between magnetron and the food ? Suppose the distance is close to the food, and if the distance is 150mm , How this would result ?
Thank you
Search for EM waveguides, I think it should answer your question.
Can anyone tell me the significance of Hartree Voltage in magnetron ?
Please put some video related to microwave transistor,hemt
It is coming by tonight
why u put r f input , the magnetron is a oscillator not a amplifier.
Its RF output
@@EngineeringFunda You should make another video with correct explanation
And sir thankx ye video dekhkar muje lag raha he ki mera microwave engineering sudhar chuka he
if we use the electromagnets inside the microwave oven then will it possible to change the frequency of microwave since many food mixture required deep heating but evenly
if rotating aperture are used than what happened
Can you put some videos of cross field amplifier
thanks sir
Hi
Thank you..
Your positive comments motivates me.
Sir plc aap data communication amd networking pe lecture banaiye
Good sir
Your positive comments motivates me.

if we use the electromagnets in microwave oven instead of regular magnet than what happened, will it possible to change the frequency instead of the time which is not suitable for many food mixture in india
Frequency, time and power are very different variables! Magnetron frequency is determined by the physical cavity dimensions. Most microwave ovens can deliver a range of power levels so that your cooking time can be what you want.
sir also give mathematical analysis of this.....
does the antenna output also generate radio frequency or high frequency alternating current?
Antenna radiates high frequency signal
@@EngineeringFunda does it only output HF signal waves? or emit high-frequency electric current?
@@kikikikiki489 magnetron generates HF only
@@EngineeringFunda ok thanks , I also want to know if we can set the magnetron frequency output to another classification ? I mean like this, most magnetrons have a frequency of 2.4 Ghz, can we change it to a frequency of Around Khz or Mhz?
Plz xplain the hull cutoff and hatree condition
Sir plz explai radar transmitter parts and recever parts briefly modulators thratron klystron duplexer video detecter etc. Plz explain briefly sirrr
Ur explaination is super but video lenght is more
I want to understand the topic reentrant cavities
thank you for the videos. May I know the software, you are using in the videos for teaching.
Inkreadble in android
@@EngineeringFunda thank you
Plz tell reference books for microwave engineering
Kulkarni for beginners, lio for pro
explain very good. but you sound like a robot. good job,
If this is oscillator then why we are providing input to it
Aamas Vasave we put dc voltage to heat up the cathode and RF input to generate magnetic fields or by putting magnets
Nothing can be generated from nothing. Energy is nor created nor destroyed right.
sir, if it is an oscillator instead of taking output why are we giving RF input?
By mistake I have done that. It is RF output.
If u give notes to each lucturer then it could be better
por favor como se podria escuchar en español
Sir , please avoid more adds. These are making very disturbance.
Why an oscillator needs RF input?
Filament is applied with low voltage AC signal not DC I suppose.
It is a an oscillator so why we will give input
RF input??? I think not.
Yeah: it is RF output
Anode shown negative at 10.16sec wrong... Anode +
Magnetorn as oscillator ????
ECE Guys
Like here ✋
sir......its RF output and not RF input if im not wrong
I'm thinking the same
Sir, why are you giving RF input. It is a oscillator.. we have to collect RF output.
Its mistake, there should be output terminal
KILLER ACCENT
Damn 😅😅
Yes, hard to understand and some points not clearly stated (I am an EE). Also, several typos in notations.
Apne bataya hi nahi k kaise cavity me electric field aaya... Kyu wo 180 phase apart rahega
there should be RF out
My question too! Talks about input but not output, unless his "input" loop is really the output.
OUTPUT KAHAN SE NIKLEGA. APNE TOH SB JAGEH INPUT HI DE RAKHA HAI
@@hyperion3704 when we switched on a magnetron or we can say just before switching on a magnetron there will be no output then from where does you feed a part of output to the magnetron.
Jab magnetron ko power ON kiya jaata hai ya magnetron ko power ON karne se theek pehle magnetron se koi bhi output nahi nikal raha.. to aap magnetron ko input kahan se denge.
Add lu ntra babu thega display aipothunay
It's oscillator then why rf input to this device?!!
Please provide 2d
Are bhaiya jra hindi me bta deta to jada bache pura video dekh lege..........
sir aap notes k form samjhaao
Explanation aroud electron bunching is incorrect!
Cev anyone?
DU-BABBA DU-BAAA DU-BABBA DUUUUH !!
2d diagram
Sir plzz provide theory
Pls stop giving add between videos it is very distracting
Use adblocker
RF input? xD
magnetron gets rf input??? xD bwahahaa xD
Sir please use hindi language 😢😢😢😢
Take this video Off. You have no idea how magnetron works.
So many adds😈😈😈
S so irritating know
