I needed this for my PTS exams which carry 50% of my grades and my teacher doesnt know how to explain properly, you just saved me thank you so much and have a wonderful day
I have a final tomorrow and I’m the biggest procrastinator you will ever meet, without your videos I’ll prob be crying right now. I appreciate your work so much you deserve way more! Thank you!
this is so helpful, I have a physics exam on Monday and cannot stop worrying about it, my teacher makes it very hard to learn information and never does practices and I am a very visual learner. Thank you so much and I will be using these videos in the future!!
Our teacher basically covered this in 3 days and we students didn't understand a bit. Tomorrows my exam. You guys helped a lot i understand much more now!
3:03 Would the compass not point to the North pole of the bar magnet? Because compasses are meant to show you which way is North and so the arrow head would be the South Pole.
Thanks cognito. You are very good teacher and friend . Keep up your good work. Best wishes and you are a pure genius. This is really helpful for the upcoming physics exams. Thanks again . ❤😊👍
hey, im kind of confused at 1:30 as to why the inner lines of the magnet are travelling south to north, but i remember the rule being north to south? do they just continue and loop round north to south like the outer lines?
@@alemi3d yeah i see that the outer lines go north to south, but for the inner lines it goes in at the south pole and goes out the north pole, surely that is south to north?
At 4:11 you show the left magnet's North Pole being attracted to the right magnet's South Pole. But what happens to the right magnet's north field being attracted to its south end, does this conflict with the other magnet's north field? Thanks
At the start of this video I was reviewed with a GCSE crash course math revision AD OF 1 HOUR 11 MINUTES AND FRICKIN 18 SECONDS. I can only imagine the screams of agony and pain for those poor unfortunate souls who could not skip that. I was not aware this was possible But HEY, you learn something everyday am I right? Rest in peace for the unlucky ones ✋😂🙏
Hi! Your videos are really helping - could you please upload some on the waves/magnetism topics in physics paper 2 in time for this friday? Specific areas I need help with include: - electromagnetism - the motor effect - generator effect
Hi, really glad you’re finding them useful! We’ll be releasing videos covering those over the next few days! Unfortunately we won’t have one covering the generator effect in time 🤦♂️ sorry about that and good luck for Friday!!
Magnetic field lines do not actually exist but are imaginary lines used to illustrate and describe the pattern of the magnetic field. The magnetic lines are assumed to emanate from the north pole of a magnet, pass through surrounding space, and enter the south pole. The lines then travel inside the magnet from the south pole to the north pole, thus completing a closed loop
Just a note on the diagram. You can't have touching magnetic field lines as the distance between the lines indicates the magnet's strength, so if they are touching, the magnet's field is infinitely powerful.

This guy explained all my science topics better in 1 hour total than about 30 lessons of science….
On Friday I have my physics exam,Thankyou so much for uploading these videos!!
You’re very welcome! Thanks for all the kind comments and support 👊
Me 2 but on thursday
i have it tomorrow lol
howd it go:>?

How’d it go I have mine in 2 days
@@BlazeKnight1_1which paper do you have, 42?
I have mine on Friday 😭😭😭😭😭😭
I depend on you for my Math exams and Science exams fully. I don't know what I'd do without these videos.
probably fail....?
silly
@@ibbagx7765 fail isn’t what he would do if these videos don’t exist. Jumping off his balcony could be one. Only the examiner could fail him.
So helpful, especially after school closures. Thanks Cognito
Cheers for watching, happy to hear it helped :)

Good luck!!!
@@Cognitoedu thanks
@@Cognitoedu your videos are very helpful

Thanks cognito. You are very good teacher and friend . Keep up your good work. Best wishes and you are a pure genius. This is really helpful for the upcoming physics exams. Thanks again . ❤😊👍
this vid made me interested in science and the next day my teacher was surprised how much knowledge i knew bc of this vid once again ty
That's great news Ong, thankyou!
This video was so helpful and straight to the point, tyyy!!
- many thanks, from a year11 student on Saturday at 00:01😅
hey, im kind of confused at 1:30 as to why the inner lines of the magnet are travelling south to north, but i remember the rule being north to south? do they just continue and loop round north to south like the outer lines?
No it is correct, the outer lines go from north to south, you can check online too
@@alemi3d yeah i see that the outer lines go north to south, but for the inner lines it goes in at the south pole and goes out the north pole, surely that is south to north?
My final exams are from next week and i am studying from your videos, thank you so much.
You are a hero! So helpful and straight to the point ❤️❤️❤️❤️
Thanks Mostafa, that's great to hear! 😊
Thanks for all the fab videos you have produced. They are very useful and summarise topics very precisely. Keep up the fab work! Thanks again.
Thanks so much for the lovely comment, really happy to hear they’ve helped you out!
My science exam is after a couple of days and I am seriously thanking you so much for how you explained it in detail I really love your video's
you taught me better than my teacher tysm🙏🙏
Tmrw is my final exam and i am Revising from your vedios thank you for your helpfull explanation
At 4:11 you show the left magnet's North Pole being attracted to the right magnet's South Pole. But what happens to the right magnet's north field being attracted to its south end, does this conflict with the other magnet's north field? Thanks
Thank you. Now acing my physics paper will be a 100%
THANK YOU SO MUCH COGNITO! I JUST FOUND YOUR CHANEL AND I LOVE IT 💕

well composed and illustrative
honestly life saving.

But HEY, you learn something everyday am I right?
Rest in peace for the unlucky ones ✋😂🙏
You are so popular in our school, that our teacher searches ur videos and presents them in out class
My exams tommorow 😰😰😰🙏🙏🙏
bit late but good luck
Goodluck

thanku loads, its so relaxing to see such helpful videos available
3:10 so is that why the magnetic north pole is actually the geographical south pole? because my teacher said that they switch somehow...
I got a 4 within a week revising on my mocks because of him😊❤
i might be cooked tommorow
Real im so fried
the geographic north-south pole shi is killing me ☠
@@na107_ its flemings left hand rule thats going to be the end of me😭
nah same💀
How it go
that is so helpful. but can you post some videos about igcse? cause i think they are a little different
plz
plz
i really need it and u r 100times better than my teacher!
@@ChanYunchenthis is for the igcse
Everything covered on this channel is on the syllabus
I have a assessment next week…gotta be revising.
Why does the compass point to the left if it always points to south? I thought it would be pointing right to the S of the magnet?
Great vid xx
Thanks Angela! Really appreciate the comment :)
where is the live video below at the description cannot seem to find it
Cheers for noticing, i've just added it - it's this one: th-cam.com/video/DMO373nDp8M/w-d-xo.html
I have a question cognito , do magnetic field lines exist inside the magnet? Thank you for picking the q
Magnetic field lines do not actually exist but are imaginary lines used to illustrate and describe the pattern of the magnetic field. The magnetic lines are assumed to emanate from the north pole of a magnet, pass through surrounding space, and enter the south pole. The lines then travel inside the magnet from the south pole to the north pole, thus completing a closed loop
They don’t really exist, they’re more of imaginary lines that describe the pattern/illustrated imaginary image of the magnetic field.
My guy is a lifesaver.
Is it bad that i study my lessons of physics from this videos instead of attending my teacher lessons?
who is in quarantine and reviewing 🙋🏻♂️
Geeky yea boi online exams
🙋♂️
Just a note on the diagram. You can't have touching magnetic field lines as the distance between the lines indicates the magnet's strength, so if they are touching, the magnet's field is infinitely powerful.
Very nice 👍
Ya’ll exams have been killing me😭 they start on Thursday and I’ve been staying up all night for three days straight trying to study 😭😭😭
Girl what 💀 ur scaring me i was not revising that much
Thanks
Amazing
Excellent
Could off learnt this in a few minutes instead of a few MONTHS.
Thank you
Who else is preparing for next Wednesday?
Doesn't a compass always point north ?
Unless you stick it next to a magnet ...
im in middle school and I can still understand it!
Damn physics today
I got a physics exam tommorow
I have an exam tommorow
Nice
sounds like mrwhosetheboss
Who's revising for their test on the same day 😅😂
I hope this revision works???
Maybe
Hi😊

Exam is on 27th march please wish me good luck
i love you
