- This video is a summary of all of AQA Magnetism and Electromagnetism, explained for GCSE Physics 9-1. You can use this as an AQA Magnetism and Electromagnetism revision tool.
The magnetic field around a permanent magnet loops from the north end to the south end and can be represented using field lines. If the field is stronger then the field lines are closer together. The magnetic field around a current-carrying wire is circular and we use the right-hand thumb rule to determine its direction. A solenoid acts like a bar magnet.
The motor effect: A current flowing in a magnetic field will produce movement. We use Fleming's left hand rule to determine the direction of movement. Thumb = force/movement, first finger = magnetic field and second finger = current.
The generator effect: A moving wire in a magnetic field will produce an electric current. This is very similar to the motor effect and again, we use Fleming's left hand rule. There are two types of generator: an alternator (AC) and a dynamo (DC)
The force of a magnetic field is given by: force = magnetic field strength x current x length of wire, F = BIl.
Transformers are used to step up or step down the potential difference of the National Grid. Vp/Vs = np/ns and Vp x Ip = Vs x Is.

Here before all the other yr 11s rush to revise two weeks before GCSE, if any one is watching this in yr 10 or below. Trust me exams come before you even realise they are there just revise long term what's going to help you? A controller or a text book. Just revise, use your time wisely
good luck in your exams when they come
Who bullied you?
lol exams are cancelled chill
@@vibekiller21yeet13 who asked
@@vibekiller21yeet13 nobody he's right
i definitely find this the hardest unit in gcse physics but this helped sm thankyou!
This is amazing, thanks I was having a lot of difficulty getting this into my head.
i dont mean to be so offtopic but does anyone know of a tool to log back into an Instagram account??
I stupidly lost my password. I love any assistance you can offer me
Thank you so much i loved the way you explained this, especially how magnetic fields, current and motion are linked that really helped me understand how motors and generators work.
Glad it was helpful!
Very easy to understand better than reading some revision work keep it up thanks
Very clearly explained. Thank you.
So helpful! Thank you!
Useful for a level
Thank you so much, it really helped a lot!
Hi, I have question if two coherent sources produce waves which are 180 degrees out of phase, what is the possible value for the path difference of the two waves when they meet at a point of constructive interference if the wavelength is lamda?
this guy may top freesciencelessons, ive just learnt more in 12 minutes than 3 months
Thank you - although I have a lot of time for the legendary Shaun.
@@PhysicsOnline love it
ABSOLUETELY AMAZING
great video, very helpful
Thank u so much man
OMG THANK YOU
very helpful thanks, could you do any videos on the motor effect please or terminal velocity
I will do
Thank you so much for the help!! I have my p15 module test coming up and this is what’s stopping me from getting to an 8. But I feel so much more comfortable on the content now!! Also random question: what pens do you use? because they look lush
The pens are the Pilot V Sign Pens, they are lush! I literally brought them because of this channel :D They are thick but nice to write with.
i wanna tell you are the second best teacher in you tube i wish you the best of luck thank you so much.
Second best?
@@PhysicsOnline lol after freescience lesson.
@@PhysicsOnline thank you again sir
I might be wrong but didn’t you draw the field around the straight wire of current the wrong way round
EPIC VID!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
is there a decent website where can I purchase magnets etc for my classes (I have no technicians)
A million times thank you for LITERALLY saving my exams
No problem
gotta thanku i have some hw due in a couple of hours
:)
I am really confused on how Fleming's left hand rule works, in the example you were using you showed the current going in an awkward position but i was unable to tell where the current was going, the only thing i could tell was the magnetic field,would appreciate if you answered as fast as you could,I have a test today,thanks.
L
Where did you purchase those bar Magnets from? Do you have a link?
BTW, that transformer made from Lego looks amazing.
I think I got these ones from SciChem.
watching this on the morning of my exam👍🏾👍🏾
Video was very helpful!😁
Thanks for giving me knowledge in a beautiful way❤️ . Can you please give lessons on topic "light " too. Light chapter is in our course curriculum CBSE. But I can't understand anything as in india, we are not taught how and exactly what a thing is! They just make us gulp the text written in the book. I know it will take a lot of effort to make a video . But please help sir🙏 .
Respect your knowledge !
Regards,
Pranav Sharma
Hope. You will reply👨🏫 my best teacher❤️
not related to magnetism but in the radioactivity topic, do we have to know how a beta particle is formed? By the way, these videos are really helpful!
You just have to know that is is a high speed electron emitted from the nucleus - that is all.
if the question comes up just say during a beta decay a neutron splits into a proton and electron. this electron is then ejected from the nucleus and is 'high energy/fast moving'.
you missed some specification content - the electron motor was missed (triple and combined Higher tier)
I'm the only year 11 here so far the day before the exam in 2024
thats me as well, good luck
EPIC GAMER MOMENT!!!!!!!!!!!111!!!!!!!!!!!1111!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1
Very helpful. Keep on the content and try to beat free science lesson😂
Thanks. Have a look at gcsephysicsonline.com It will (eventually) be a full physics course with everything you could ever need.
GCSE and A Level Physics Online Oh thanks. Is that all I need to know for new AQA spec. Because I really don’t want to miss out any key points because some teachers do not teach the HT content. Also, is it better to use your revision guide while listening the revision videos
@@bobbythepianist828 It is worth using the guides, so you can check off the things you have covered in the video - if you're still not sure then watch that bit of the video again, use other videos or go back to your own textbook, notes and revision guide.
No, Freesciencelessons is totally different, he is the guy u can rely on for passing science gcses but physics online is the type of person u can rely on to get straight 9s in physics
why are there 3 dislikes??
4 now
Studying Magnetism in 12 minutes is a disgrace.
Lol we watched this in our physics lesson
I follow so far until the motor part I don't understand it as English isn't my first language
If you look on my website you’ll find extra videos that explain this part in plenty of detail, that should really help you.
@@PhysicsOnline thanks, but do you have one for biology and chemistry?
I checked your site is there cie IGCSE?
Me a month bfore gcse dying watching this
