A Level Physics Revision: All of Electromagnetism (in 38 minutes) 

Thank you for helping me get an A in OCR A physics last year in 2023! I was predicted a B but your videos helped a lot in me obtaining a grade A. After all the hard work I’ve also successfully got an unconditional offer to study medicine this year! Thanks again

I wish the best of luck to the people, including myself, that are learning the content just before the exam.

this man carries my physics grades. your videos are a great revision source. thank you :)

FBI is the best way to remember Fleming's left hand rule. F = force (thumb) B = mangetic field (index finger) I = current (middle finger)

Next step: practice questions walkthrough: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-N8jUe1DPuNw.html Hope this is useful! : )

What a lecture! Hats off. Helped me real good.

You should definitely do a video on Hall Voltage, as I see that it is missing. These videos are amazing!

revising for my board exams right now, although this is for OCR, it is immensely helpful for CIE as well, thank you so much!

mocks coming up, this is very handy :)

Best lecture on electromagnetism. Keep up the good work Sir✌✌

You are insane, helping me finish my a level physics faster! Cheers boss

My favourites channel for a level physics. well explained

Thank you for this great resource!

Thank you so much for the amazing video!

Fantastic Video, Thank you!!

lovely stuff thank you sir, actually quite similar to AQA spec as well !

Wow wow wow ,I am amazed ... You did an incredible work here ...now I can finally understand magnetism🎉 . God bless you sir ,continue with the good job 🎉🎉

Yoo really neat lecture. Good job

Thank you very much! You have once again helped me improve my physics grade!

Thank you so much bro. I have A level physics exam today , paper 2, and your video helped me a lot to understand electromagnetism. Lots of love for you bro❤️

Thanks so much, this helps a lot!

Outstanding lecture 👍👍👍

best channel ive come across since you cover the same board and teach brilliantly, thank you very much. lets not forget the drawings too lol.

Your Videos are just soo good

Really Helpfull💯👍

I love it for simplifying it that way thanks

Great video thanks!! Would it be possible to do a video on the possible experiments for elctromagnetism please? Your materials video was very helpful.

Is this called 40 minute magic??? Thank you sooo much sir God bless you. And pls pls pls keep uploading more videos

Hello sir, did you make a video on the graphs that are in EM induction B VS T graphs, the ones with the weird shapes, sometimes rectangle etc

7:28 Using Right hand grip rule on the diagram, wouldn't the North-pole mentioned in the video be South-pole instead and vv? According to the fact that the for a cross sectional area of a solenoid, if the current is flowing anti-clockwise, it is North end of the pole and if it is flowing clockwise, it's the South-pole, the diagram is again reversed.

POV it’s 3 hours before the exam

Sir, thanks a lot. Your videos are helping me a lot. I am revising all the syllabus of physics with the help of your videos which is my life savior. Can you please upload a revision video on Alternating Current (AC) it will be very helpful for me Thanks 😃😄

Best A Level Physics channel

For the magnetic field around a solenoid, how do you know for sure which end is the North pole? Is it the right hand grip rule, because when I try to use that my direction for the magnetic field changes depending on which end I look at (if the current is going up or down).

for 33:25 , if we have to find the emf, would we have to draw a tangent at that point, and then find the gradient of the tangent?

final is tomorrow, thank god for this video

Nice one dude

7:07 ....but wouldn't the magnetic field be travelling from A to B in the front and B to A in the back , since they have to run a full circle. So why did we assume only the first case to be the answer ?

I religiously recommend this youtube channel to my friends lol, no other channel compares to the understanding I gain from you bro

Sir could you please do a video going through electromagnetic revision exam questions these videos are so helpful !!

20:32 I’m pretty sure the diagram next to it on the right is the one where the field line is parallel to the area sir!

in the edexcel book they used Φ=BAsinθ instead of cos. so i guess the graph here 32:15 would be different too, since sin90=1?

So, if I understood BILSinTheta correctly, then the electrons move in a spiral in the direction of the current flow?

Thank you!

Excellent drawing Z. I appreciate the video as always, helping me prepare for next months exam....

hi sir, what do we need to know for an AC generator (OCR A)? do we need to know the brushes and slip rings? or just that the rotation of the coil causes change in flux therefore emf and current induced?

Hi again, at 3:10 'current' into the screen is a cross, but at 13:51 a cross is the 'magnetic field' into the screen, just wanted to clarify why that is different?

Hi!! Thank you!! It has helped so much!! Have you got anywhere I can get the notes?

Life saver

i saw very good thing on you. this vid initiate some ppls like me

5:43, please was that Fleming's right hand rule,am confused

thankyou soo much

Why haven't you included the hall effect and the current balance method?

appreciate your drawing

What kind of practical skills could they assess to do with Electromagnetism?

Is this video alone enough for the exams?(With ofcourse Past Paper practice)

What do they mean when they say the core of a Transformer is laminated?

1:15 why is the the North Down and South up while it should be the opposite

which software is this

thanks

4:10 damn good drawing tbf 😭😭

at minute 32.00 why does the normal change ?

tysm

is Motor effect in the ocr spec?

30:04 there is no link in description

I hate magnetism; praying to god that there isn’t a 6 marker on magnetism in OCR P2 or P3

If you were a stock, I'd invest in you rn!

Why do they teach Flemming's Left Hand rule at school? At uni right now all I ever use is the right hand rule for all cross product based stuff including EM. What's so special about Flemming's Left Hand rule?

Another way I use to remember 11:33 Fleming's Left Hand Rule is "FBI"

What's "A level" in your country? I keep seeing this term but does this mean college level or high school? I'm from USA, sorry

is this a part of as level?

For what exam board is this?

Is all of this a part of 2023 syllabus please tell me

I love transformers

I write my physics exam today ;-;

Father( force)mother *magnetic field )child (current )is better

+++False! There are no 'field lines. Stop confusing lay ppl including many professional. What 'field lines' are, are 'magnetic equipotential lines' which is another way of saying 'lines of same strength within the field' or 'lines of same energy density within the field' [akin to isobars. And, since there is no 'flux' [as commonly defined' 'flux density is another misnomer' I've just demonstrated the gross misunderstanding academia has of physical sciences. What are the Properties of Magnetic Field Lines The tangent drawn to the magnetic field lines gives the direction of the magnetic field. The closeness or density of the field lines is directly proportional to the strength of the field. Magnetic field lines appear to emerge or start from the north pole and merge or terminate at the south pole. Inside the magnet, the direction of the magnetic field lines is from the south pole to the north pole. Magnetic field lines never intersect with each other. Magnetic field lines form a closed-loop. Field lines have both direction and magnitude at any point on the field. Therefore, magnetic field lines are represented by a vector. They denote the direction of the magnetic field. The magnetic field is stronger at the poles because the field lines are denser near the poles. Obviously mostly wrong. You are so full of yourself [self-important]! === I'm formulating the PARALLAX ELECTRIC THEORY which dispenses with the idea of magnetism which is but a historical anachronism, a misnomer, for matter having structured/organized polarity [positive and negative charge] via matrix/lattice/crystal/geometric-molecule/alloy units [depending on it's construction]. The concept of mag lines of force is another antiquated anachronism. In support of the aforementioned, all electric and magnetic fields are measured using the same equipment - magnets, coils, etc. ++++++So You Think You Know Physics.
