Magnetism and Electromagnetism REVISION PODCAST (Edexcel IGCSE physics topic 6)

This revision podcast is for Edexcel IGCSE physics or dual-award science (4PH0 or 4SC0), and covers all of topic 6 - magnetism and electromagnetism.

0:13 Permanent Magnets
1:56 Induced Magnetism
2:35 Electromagnets
3:38 Motor effect
7:16 Loudspeakers
8:17 Electromagnetic induction
9:45 Dynamos and generators
11:48 Transformers
14:04 Power Distribution
15:46 Summary

This video replaces the previous revision podcast on my channel with better quality sound and a few updated slides.

I just wanted to say thank you for saving my Physics GCSE, which I sat last summer, but had previously struggled so much with. I am now doing Physics at AS level and intending to carry on with it next year, and I don't think I would have had the faith to do it if it were not for your informative and well-presented revision materials! Thank you so much for doing these videos!!

THESE VIDEOS ARE SAVING MY LIFE! GCSEs in 1.5months and now I might actually do well... Thanks Ben!!

Shout out to them people who are watching this video one day before the exams. Good luck for tomorow 👍🏻

The field on the "outside" of a bar magnet is from North to South. If you think about the "inside" of the magnet, the field would be from S to N. You can actually be inside a solenoid - where the field points towards the end that becomes the North pole, and then THROUGH the North pole, so that the field on the outside of the solenoid goes from its North pole to its South pole.

I know this is from 10 years ago, but this series has been the lifesaver of my entire school year, because of this series, I was able to get good marks despite studying last minute.

Great video! This topic is very confusing so thanks very much!

[TubeYous]

Cheers man, great video. Doing my GCSEs next month.
Just one thing - at 6:17, it show a right hand, but should that not be a left hand?
Anyway thanks again

[bendjtrix]

Everyone saying they watching this months before their gcses whilst i have mine tomorrow and this is my first time revising. Bish whaaa 😙 ✌

[lilzanta]

wow... 5 years on and still works great... thanks Ben

[AbiSheppard]

Uhh isn't the hand used to show "fleming's left hand rule" and 6:18 a right hand?? It looks as if its been flipped because the letters are the wrong way round.. Just thought I should let you know as this confused me greatly until I realised it was the wrong way round! :)

[moochimichimoo]

thanks you! i've got the exam later today and i really needed some clarification on electromagnetism.

[cam]

at 3.30 it says the thumb points in the direction of the magnetic field lines, yet it is pointing from south to north? shouldn't it be north to south?

[ftyhbn]

at 3:37 the right hand thumb rule, wrapped fingers represent the magnetic field lines right? not the direction of conventional current

[feskii]

Are the topics you are explaining simplified from The Edexcel IGCSE book? or are there stuff you are adding not from there??
And can you briefly explain how you would know how to position your left hand, by that I mean how would you know if the force is going up and down, left or right

-You are the Best, Hope I ace my mocks

[SaphireRoseAcorn]

This absolutely amazing, thank you so much Ben Ryder! I wish you could do this for all my subjects! Does anyone know anyone remotely similar to Ben's podcasts for IGCSEs or good revision websites for especially all the sciences, and core subjects? If theres more than thats good too! Would be a real help for me

[benaryder]

Lenz's Law is not specified in the IGCSE Edexcel syllabus, Nicholas.

[pratikgpt]

thanks alot..this really helped me clear my doubts

[xVENx]

thx that helped a lot, but can u make an updated version since they updated all the books?

[hbazaham]

Thank you so much...I need an A* and this is really helping me out. You are a brilliant man and again thank you so much for you're videos might have just saved my grades.

Ps. Would you consider making IB physics videos next year, just a thought.
