Magnetic Field Created by a Curved Wire

Physics Ninja looks at a problem of calculating the magnetic field produced by curved wire segments. Biot-Savart law is applied to 2 cases and the total field is evaluated

So simple and clear. This is much appericated by so many of us, thank you!

Thanks Physics Ninja! I just had my exam; feeling quite confident thanks to your help!

[manfredvonrichtofen]

I have an exam tomorrow and your explanation saved me :D thank you so much!

[debbiechan]

Thank you so much for this. You saved my assignment!

[taladiv]

Thank you for your straight-forward explanation video.

[arandomdude]

Thank you very much! It sure does seem simple when you explain it!

[shreyamurali]

Thank you so much for such an amazing and simple explanation ! :)

[ginaherrera-ds]

I don’t understand how for the second problem the magnetic field is pointing into the page. Can you explain that, thanks !

[SUKANIA-jijc]

Hello sir,
Watched and learnt from videos . Thanks.

[sruthilakshmis]

Superb explanation . Thank you so much 🤗

[mulatiedemis]

Hi physics ninja would you mind inform the book you used as a reference?

[tienhuynhdung]

thank you so much, i subcribed this channel because it is so worthy!

[gabzinemo]

Thank you so very much for the great help!

[tcy]

is it convention that out of page is positive and vice versa for into the page?

[shailajaprasad]

in the first problem, how can we calculate the direction of the resultant magnetic field at the point o?

[priyanshudan]

Please try some IIT JEE Advanced problems sir, we Indians would get much help from your videos

[englathysell]

Why is B2 into the page in the second example?

[donovanrao]

I dont understand into or out of the page to find + or -. does it not go into the page on one side of the wire and out of the page on the other side of the wire for both 1 and 4? Someone please help! 😭
