I finished my physics degree last week, and I'm watching all of these videos to refresh / summarize what I've learned. Even some of the introductory course videos are unwinding things in my brain and making them much more clear. Thanks for the vids!
The B Field outside of the solonoid is not = 0. Every wire of the coil has a circular B Field around it and some of that B Field is outside the solenoid
You are completely correct. Well done. The field outside the solenoid is not zero, but typically much weaker than inside, so we approximate it as zero. Cheers, Dr. A

You're very welcome.

I just finished my EE degree at WSU (Vancouver) this week, your lectures really help me get through it :). Thank you so much, Dr. Anderson.
Congratulations! That's great news. Glad I could be of help.
Cheers,
Dr. A
My favorite part of this video is that you could make your homemade magnet!
Mr matt Anderson this is not what I am looking for I what how did Integral of B.dl vector is become equal to Current inclosed Hope you will answer it

Just realised, he is writing opposite.
Tnx for the explanation sir 👍👍
Why is magnetic field outside the solenoid 0? If that's the case, there exists magnetic monopole... There should be a factor of 2 missing
how is he writing backward or from right to left ???!!

I like how professor reply to every comment..I love you already you have brought so much help to my life
Sir i am in 12th class and ur lectures is fully matchings with my 12th phy syllabus so thxx to provide us such a gem type of content ....
Surley there will be values to plug in right? Or i will have to find them ?😨😨
Surely*
you spelled it wrong
The best Physics teacher in the World !!!
I didn’t even finish high school. How did understand this??
Glad to have you back. Keep working your way through these videos and you should get a good basis for understanding.
Cheers,
Dr. A
Great video....got to sneak-in an integral...nice! :D There are lots of relationships between I and B. Very versatile part of physics.
Glad you enjoyed it!
Cheers,
Dr. A
