GCSE Physics - Motor Effect #79

In this video we cover:
- What the motor effect is
- How to find the direction of the force (Fleming's left hand rule)
- An example of the motor effect using rails in a horseshoe magnet
- How to find the size of force (F = B I L equation)
- An example question using equation

2 days till the real exam and this is the first time im revising physics🔥

[hoop]

Typing this at 5:29 June 15th 2023, heading into my final GCSE (physics paper 2) tomorrow and doing some last minute revision.
Genuinely want to say thanks Cognito, wouldn’t have be getting were I want to without this channel.

Bro your carrying me in the mocks without even knowing me 💀💀

[tiffny]

i couldnt understand the motor effect at all and now i dooo!! youre amazing

you can remember it like this:
Thumb points towards Thrust (force)
First finger points towards Field of magnet
Central finger points towards Current

Last exam. Thank you for your help throughout this year. Thank you cognito I will always stay subscribed.

You literally have videos covering every single aspect of the gcses, thanks a million!!

[whiterappersworstenemy]

Explained what my class physics teacher nor edrolo couldn't seem to teach in a clear and compressed manner. Thanks m8

[potatopie]

Please start doin ALEVEL Maths and science. I genuinely don't know what imma do without your videos . the explanation is so clear and easy to understand unlike the textbooks. and the pictures are really helpful aswell especially if its a moving thing which a textbook image cant show. Thank you so much for doing these videos tho I genuinely do owe quite a bit to

[localbookworm]

i honestly dont understand how y'all are not more popular

I love Physics, despite those times when I feel some lessons are impossible to understand better without practical and visual demonstrations and I can't manage that. But the editing in your videos comes as a live-saver here. The art, clarity and simple language through which you explain the topic is just beautiful! Thank you so very much!!
I will always stay subscribed.❤️❤️

[ashleymadziyire]

You know what i like about this guy----> He actually helps😊. No offence but with my physics teacher it's tough honestly😢

[xsjpdex]

I have my physics unit 1 paper (wjec Wales) on Monday - this helped loads thank you so much!

[eileenl]

Only video that has actually helped me understand the topic, I'm too happy that I've found this

[roshanfatima]

THANKYOU SM I WILL PASS MY EXAM BEC OF YOU & TOM TOO!!! TYSM 4 THE ANIMATION ^_^ TYSM !!!!

[ollie]

Perfect timing! was wanting to revise this and then i got the notification :)

[blueberrybubbly]

Thank you so much I have a physics test tomorrow and you helped me so much. I'm a new subscriber btw!!!

[JCL-nvjk]

Thanks for this as this is now part of the aqa combined science foundation spec, despite it being higher tier only prior, and I hadn’t learnt if before
