If the time period for one rotation is given by that equation at 17:55 surly you need to half that to find the time for 1 half rotation and then reciprocate it to find frequency. so F should be BQ/pi*m?

People like you deserve a special place in heaven. Man be carrying us around in A2 physics.

1:15- direction of current 2:14- centripetal force on a charged particle 7:00- particle detectors 9:00- mass spectroscopy 13:20- cyclotrons

You absolute legend!!!!! I could never understand this before.

Up at half 5 in the morning watching your stuff ahead of the exam today, you're a life saver

I recommend this video to anyone like me who struggled to understand cyclotrons / mass spectrometers. They are very well explained and help with the understanding of the topic

"Deez Nuts" haha gotchu at 13:49

You are very much up there with the greats such as Mr Trifon Madas (rip). My goat, thank you for being more useful than my teachers could ever aspire to be

i just dont understand why ppl dislike those type of vids .... like this guy is tryna save your ass here

Just found your channel, love it already!

Flipping off physics at its finest 1:51

This may be off topic, but I think someone might find it interesting. :) Device to end the creation of Nuclear waist. Electric Generator Design that's powered by it's self & perpetuates more electrical current then is needed for it to run continuously on it's own. Step 1: calculate how much energy you need pumped into an electric motor to make a vertically positioned circular platter with magnets in-bedded horizontally around it's left side and right side (so there pushing force is pushing out sideways relative to the vertically spinning disc) to spin as fast as you need it to. Also better to make sure these magnets are shielded around their sides & back with metal that has high permeability so the magnetic field they are emitting is focused fully out sideways. :D Step 2: Calculate how many sets of copper coils you need to be interacting with magnetic fields to achieve this & to perpetuate more electrical current flow then is needed. :D Step 3: Build a round horizontally positioned platter covered in all these copper coils pointed down that does not move (Is stationary) :D Step 4: build a round platter covered in powerful magnets pointed up that can spin and place it directly under platter with hanging copper coils. :D Step 5: Position the vertical platter that is motorized close to the horizontally positioned platter covered in magnets pointing up so that when the vertically positioned platter spins the in-bedded horizontally positioned magnetic fields slam sideways against the edge of the horizontally positioned platter causing it to spin. :) Step 6: Make sure enough of the copper coils are feeding their electrical current into the electric motor and the rest of the copper coils are linked into a set of rechargeable Battery's placed in the closest most convenient spot. Step 7: Build a duplicate setup of horizontally positioned discs with hanging copper coils and disc with upwards facing magnets and assuming the first set of discs are positioned to the front left side of vertical spinning disc, position the other duplicate structures to the front right, the back left and the back right of the vertically positioned motorized disc. As the vertically positioned motorized disc spins the horizontally in-beaded magnets will now hit into all 4 horizontally positioned discs causing them to spin. so you will effectively be using the spin of one disc powered by one electric motor to spin 4 constructs that are each generating electrical current. now build this whole setup multiple times over and use the current perpetuated by it to power up scaled electromagnetic generators that are equal to or more powerful than the ones used in a nuclear power plant. You will now have a device that is self perpetuating off of it's own electrical current perpetuation and no nuclear waist to worry about.

2:28 what's the paper ever done to deserve that?

Amazing set of videos! Great for crammers like myself

Hey thanks for the videos, they are really great

best explanation of mass spectrometry and cyclotrons ive seen, thank you, defo think mass spectrometry will come up in aqa paper 2

+Science Shorts I think that the transformers and the capacitors video should be in the fields play list as well as it is in the same module, just a suggestion. Great Videos btw!

God bless you sir!!!! beautifully and well explained!!!

Great explanation as always👍.This helped me a lot.😊

Thanks so much for your excellent lectures.

thank you for this video. really saved me in my paper🤓🤓🤓

Really good video!

great video, thank u Sir

Thank you !!!! You are reeeeeeeeeeeally amazing!!!!!!!!!!

I remember the semi circles by 'dees nuts'

Amazing!!!

dees nuts

thank you you explained that perfectly

can you please do a course on digital electronics, flip flops etc, you are a really great teacher

Your explanation on why a charged particle will spiral (the whole horizontal component of velocity not being affected by the magnetic field )was spot on.

Great video! - in the velocity selector you consider the force do to B and the force due to E, what about the force due to gravity? Is that so small we leave it out?

very good video, i like thumbs 🥳

(I am a complete idiot) + (I understood all your explanations) = (YOU 'RE GOOD) x (at explaining). Thank you !

How do charges that the source emit randomly in time get synchronized in phase with the gap voltage? What happens to the ones that arrive at the gap but the voltage is of the wrong sign?

13:19, "not the name of a transformer" 😃 I terribly miss that magnificent series (1986 - 1990)!

Am I right about saying that the magnetic field lines go into the page for the cyclotron but only inside the dees? It's took me over half a year to understand these and your videos help so much, thank you :) *edit* Also why doesn't the magnetic field alter the speed of a proton in the cyclotron inside a dee when F=BQv which shows that B is proportional to v?

You’re awesome

nice

*_I LOVE YOU_*

Hi! Where can i find an explanation for Hall Voltage?

I will love you long time if you make one of Polarisation and EMF. You've basically been carrying me through my A-Level, thank you so much senpai

4:14 is it spiralling inwards or is it spiralling in a perfect cylinder with no change in radius because I'm not sure if I'm getting it confused with part 7:29

Hi just wondering, 9:30, the direction of the magnetic field is going into the screen. By using flemings left hand rule wouldn't for force on the positively charged particle act upwards? Seeing as current is flowing from left to right?

8:11 would this not work though for pair production as pair production only produces a particle and its corresponding anti-particle therefore a proton or an anti-proton or an electron and a positron could be made not a positron and an electron from pair production?

I don't understand why the electron turns around at 3:47 it seems like it should just start to turn then go the other way, not spiral back again

For people doing OCR A we don't need to know about the CYCLOTRON as its only in the aqa spec right?

If you were accelerating an electron in the cyclotron would it spiral the other way?

Cyclotron sounds like a name of a transformer lmao

I'm pretty sure the time period of the AC in the cyclotron should be halved, so therefore the overall frequency is doubled. Is that correct?

What is the definition of a feild?

Could the ion have a bigger radius due to it having a higher charge then an electron assuming it has more then one proton?

I haven't even started my A-Level Physics course yet just finished me GCSEs. I'm just watching these vids cuz Physics is so interesting... and I want a bit of a head start😊

i think you should have include magnetic fields in cyclotrons a bit more like there is one magnetic field plate on top and one on bottom which makes the charge go in cirlce in the dees as there is no electric field.

Its not dee's its deez nuts....

Dees....Dees nuts:D

just me that almost breaks my wrist in trying to work out f,b,i in flemmings left hand rule?

glory to the teachers

hahaha dees nutz

Could you do physics turning points pls for AQA

Bruv last video the guy side it's the right hand rule is it just a up down side ways rule or something

are cyclotrons still in a level syllabus?

Shouldn't the frequency be twice the value you have just stated as it needs to change every half-period?

Can u make some videos on A-level astrophysics?

What about the weight of the ion?

you dont have a video on hall effect

Cyclotron Dees are like a Babybell

You lost me where the free electron is actually moving the opposite way using the Fleming's left hand rule. Why does an electron move the opposite way if it's going the other way? I'm confused :(

Dees nuts

u have missed synchrotron

oh fr, i didnt ask
