- Okay, we know that current carrying wires can experience a force in a magnetic field, but what about a current loop? What happens to that?
Physics with Professor Matt Anderson
Thank you for all the videos I’m so tired the past two weeks haven’t been able to study I’ll be back to watch these and learn thank you again Dr Anderson!
Sounds good. Get some rest and we'll be here when you come back. Have a great break.
Cheers,
Dr. A
Seems it was my right time to get to these but your teachings hit differently, Dr. Anderson. please thank you
I find your lectures very straightforward and simple. love it!👍 Well done keep making more videos.
Thank you, I will.
Cheers,
Dr. A
Greetings. I am Pakistan and i want to thank you because it was very hard to understand form my textbook but you teach it very nicely. I think that i can't forget it ever
Thank you, Professor Anderson ....we all love you in Africa too... your lectures make physics look like so much fun...and i can't wait to persue it beyond getting a digree
Clearest explanation I have seen yet!
Simple, easy and straightforward.
Cool cool bean beans.
Cheers,
Dr. A
Thank you. I am really enjoying your videos. I loved physics in college. Did well too. Wish I had pursued it further.
Not too late, come on back.
Cheers,
Dr. A
@@yoprofmatt I'm 60 years old. Grime Reaper might think otherwise.
This was great.
Thanks for another awesome video!
Love from Bharat
You sir, are awesome
thank you
You make great videos and I sincerely appreciate them, if it weren't for you I'm not sure how i would find this information
Great to hear. Of course, much of this information can be found in textbooks, but I'm very happy to help.
Cheers,
Dr. A
Hi dr.matt i want to ask why we have to time the angle between B and plane's normal?
Thanks for this. If the bottom section of the loop is fixed as a hinge, can you comment on what the torque of the loop around that hinge would be.
I understand that F=mu×B=NIABsintheta gives the torque of a free loop as here, but was just wondering if that would be the same torque around a section fixed as a hinge. I suspect not. Can you confirm this.
The reason I ask is I'm doing a problem that asks to get an expression for such a torque (due to an unknown B field) around a fixed section as a hinge . And then asks to equate this expression to the torque due to the weight of the loop around that hinge. So we can find the target variable B.
If you comment on this, I would really appreciate it.
Does the magnetic field itself have a torque or just the wire creating it
Excellent question. Yes, fields themselves can carry angular momentum and can therefore cause a torque on an object. There are many experiments showing how photons can cause objects to spin. Pretty darn cool.
Cheers,
Dr. A
Dear Prof. Anderson.
I have a theory that might change all physics and the way we perceive reality.
I await your paper! If you're serious about it, you'll need to get it into a peer-reviewed journal. There are many, of course, and here's a list:

Keep going, you can do it!
Cheers,
Dr. A
@@yoprofmatt Remember how Michael Faraday started with Sir. Humphry Davy? let's say that history might repeat itself here.
I am a Syrian citizen living in Turkey and I assure you that you will be surprised if you read my paper. I will be glad to send it to you if you want.
Is it not r x F ???
When do we use τ= BAIN cosθ and τ= BAINsinθ
Sin when the square circuit is placed parallel and Cos when the circuit is at an angle
Where did the 1/2 go?
At 9:30? We added two quantities that were each 1/2 * something. 1/2 + 1/2 = 1
Cheers,
Dr. A
@@yoprofmatt we have a sum of 1/2 (ILB) + 1/2 (ILB) it should give us ILB, where is the squared L coming from ? I'm lost
exactly.... do u know where?@@imaginary_pies
Thank you for carrying my degree
You're very welcome. Hope you're continuing or getting a great job.
Cheers,
Dr. A
