Hi sir just a small suggestion to label the videos as AS or A levels as it will be really helpful to identify which videos are related to the topic. Thank you so much!
When you said the only thing that could cause an induced emf is a change in magnetic flux linkage, does just cutting lines of magnetic flux (with no change of magnetic flux linkage) not also cause an induced emf?
excellent question so by "cutting through" lines of mangetic flux we are moving a conductor through magnetic flux and hence there is a changing magnetic flux linkage.
@@zhelyo_physics Ah okay, it's just weird though because none of the components of faradays law (BANcosθ) change do they? So how is there a change of magnetic flux linkage when its components (BANcosθ) don't change?
Hi, your videos are very helpful. We are going to have our As level exams in Pakistan 🇵🇰 ,starting from 14th May. First is the P2 and then others! I was hoping if you could make a CRASH COURSE video about difficult topics! That would take off loads over our shoulders, who are preparing for the CAIES! Thanks for the help!
I got the electromagnetism work book yesterday, and finished going through it just now, and I just wanted to say thank you so much! I haven’t revised electromagnetism yet so this was amazing, it made me more aware about the understanding behind the topic because the questions nicely built on to each other. Though side note, for faradays law in my AQA formula booklet there is no negative sign for Faradays law ( Nф/t) and for magnetic flux it doesn’t mention cos0 but only states ф = BA. Is there a reason for the negative sign and that AQA only gave one part of magnetic flux equation? Otherwise, I’ll definitely look into other workbooks you’ve made though!
thank you so much for the comment! Fantastic to hear!! The negative sign is actually crucial as it's essentially Lenz's Law. The AQA booklet gives says it just gives you the magnitude of the flux which is more confusing in my opinion at least, so I prefer to express it in terms of Lenz's Law with the negative sign. I do think that all formula booklets across exam boards should be standardised as the physics is the same, but different exam boards give slightly different quantities.
heyy great video as always, also how should I be revising from now till the exam as I really wanna score an A star but im still going over content again
I will do my best prior to exams, they do take a massive amount of time to make but this may be the next one on the list. Thank you for the suggestion.
I think the only way this can be objectively answered is by looking at the examiner's reports. They often mention what mistakes were most common and provide quite a lot of detail. I recommend that along with the past papers. Hope this helps!
definitely okay for all exam boards, electromagnetism is covered by all exam boards in a very similar fashion, hence the booklet. I will do some exam board specific workbooks on certain topics only.
so the mass of a neutron is higher than the mass of a proton which makes it possible. A neutron can turn into a proton whereas the reverse does not happen when the proton is isolated ( so far as we know). It can happen in the nucleus though. Hope this helps!
Hi! So these are mostly learned before university and then the more mathematically rigorous formulation of these concepts is studied in year 1 mostly and somewhat in year 2
It would be awesome if you could solve some of the CIE physics past papers. Especially Paper 4, with your explanation it would be easier to understand the reasoning questions. Thank you for this video.
@@zhelyo_physics Okk sir please help me because I want to give a physics pg entrance exam ( IIT JAM) and quantum is major subject so sir please start a series
How is revision going? Should I do massive video like this one but on every single point of the spec? Hmmmm : )
yessss
Yes please
yes please
Yes please
Please boss
This video is insanely helpful! Thank you again!
Anytime, thanks for watching!
This video was super helpful! I'll definitely re-visit this video before my exams.
thank you so much for the comment!
This video is amazing!!
thank you so much!
Awesome!
Video suggestion : edexcel paper 3, maybe a walkthrough one of the past papers.
thank you!
Always the goat !! Looking forward to see some videos of go through some as past paper ❤❤
thank you so much!
1 to 1 interaction of a photon emitting an electron in the photoelectric effect 🙌
thanks for this helpful video! And I’ll definitely be using the workbook
fantastic to hear! thank you for the comment!

@@leuanjennings9929 they do actually as BAN/t=BAxM/t and hence x/t is the speed
@@zhelyo_physics okay thats cool, what are M and x representing in that equation?
Video suggestion - AS spec physics revision videos
thank you

@zhelyo_physics aaah! That makes sense now! I agree the formulae should be standardised for all exam boards to avoid confusion. Thanks again!
thank you so much for this video. however, can you make a video explaining emi and charged particles?
thank you for the comment! Sure! Covered in the relevant chapter here: ua-cam.com/video/RjY5bZ4Bl8o/v-deo.htmlsi=pL5mSBlpETflevH2
heyy great video as always, also how should I be revising from now till the exam as I really wanna score an A star but im still going over content again
Thank you so much! I think a mixture of timed past papers and content is crucial. Good luck!
@@zhelyo_physics Should i just do past papers or shall i also do topic based questions?
Thank you King God bless
Anytime! Thanks for watching!
Do you think you will do a waves workbook in the near future?
I will do my best prior to exams, they do take a massive amount of time to make but this may be the next one on the list. Thank you for the suggestion.
@@zhelyo_physics I’m in year 12 so I’ve got ages 👍
Hi sir, just wanted to ask, what topic or module do you think has the hardest / trickiest past paper questions for OCR a level physics?
I think the only way this can be objectively answered is by looking at the examiner's reports. They often mention what mistakes were most common and provide quite a lot of detail. I recommend that along with the past papers. Hope this helps!
Is the one shot revision video out?
working on it! : )
@@zhelyo_physics will it be out today?
not today but this week : )
@@zhelyo_physics oh oh, my exam's on Monday
Thank you
Anytime! Thanks for watching!
Are the exam EM questions linked okay for all exam boards in particular edexcel?
definitely okay for all exam boards, electromagnetism is covered by all exam boards in a very similar fashion, hence the booklet. I will do some exam board specific workbooks on certain topics only.
@@zhelyo_physicsokay will be doing those, thank you!!
Sir please how isolated neutron can
Ever be change into proton
Also sir please bring some S level physics question
so the mass of a neutron is higher than the mass of a proton which makes it possible. A neutron can turn into a proton whereas the reverse does not happen when the proton is isolated ( so far as we know). It can happen in the nucleus though. Hope this helps!
@@zhelyo_physics sir could suggest me a good theory content for modern physics for jee advance level
This is great
thanks a lot for the comment!
Hey there, I'm from india!
Just out of curiosity, in which year of engineering do you learn all these concepts?
Hi! So these are mostly learned before university and then the more mathematically rigorous formulation of these concepts is studied in year 1 mostly and somewhat in year 2
@@zhelyo_physics Ahh i see
Where is this though
Like in which country
Is it do something with 9702 I have exam on 16th 😢
Hi, you have paper 4 right? It examines a lot of the things mentioned in the video/workbook. I hope everything goes well! Good luck!
@@zhelyo_physics Yha sir thank you sir
You could potentially do a few videos on past modelling papers 👀 js 😂
Here is a playlist : ) ua-cam.com/play/PLSygKZqfTjPCuytpobPNdrLlcqePzXIq8.html
