Magnetic Field of a Wire

032 - Magnetic Field of a Wire

In this video Paul Andersen explains how current moving through a wire will generate a magnetic field tangent to the wire. As the current increases the magnetic field will increase and as the radius from the wire increase the magnitude of the field will decrease. When the current in parallel wires travels in the same direction the wires will experience a force pulling them together.

watched you in 8th grade science classes, still learning from you as a sophomore in college. thanks for great vids!

[markthompson]

2 pi r is the circumference, not area

[nonameless]

this is my favorite science youtuber. everything always makes sense. Thank you, bozeman science

[lanasexton]

It has taken my professor 10 hours (5-2 hour classes) to explain what he has explained in 3 videos averaging 8 minutes each. 24 freaking minutes!

So I am in the middle of this video when I start hearing weird noises around my home here in France.
apparently 2021 just happened ... anyway, resuming the video.

You did great! I loved your visuals. I am 33 trying to figure where I am getting him from in my music studio. This helped me tremendously. Now it’s time to experiment and find how and why

[tortreks]

I love how you included the history of the discovery! It helps for some reason... :)

Why all of these great teachers are on YouTube 🥺 thank you ❣️ Sir

[Breyerloverever]

These videos are certainly some of the best explained science videos I've seen, keep it up. :-)

You already speak English. Part of the image cannot be seen due to caption screening. But thank you very much for your work. It benefits.

[AlyxGlide]

Mr. Andersen.. what a surprise, I'm learning!

[zaibchohan]

you're great teacher never seen before.. keep it up

[ibchemvids]

Cheers Paul, I gotta teach this tomorrow and it has been a while.

Thank you, you saved me!! The diagrams are very helpful to understand the directions of forces for parallel wires

[snmcdonald]

Right hand rule = conventional current flow
Left hand rule = electron current flow

[Moshitachi]

Mr Anderson, to tell the direction of force acting on the blue wire due to the magnetic field of the green wire, we should use Flemming Left Hand Rule.

Hi! Just saying you are a great teacher! I love learning from you! Specific and interesting to watch!

[jameselliott]

What is really needed is a video that shows the difference between wire sizes and number of turns on coils that would actually be used in motors and generators. With and without ferrite or steel cores. Driven as motor and non-driven as generator. Loosely and closely coupled. That would be very useful information to builders.

I have a diagram I would like to share with you. Coils coupled in such a way that most people would think they would cancel each other out. However they do not.

you're an amazing teacher thanks!

[ssiddiqui]

nice video and very thankful to understand about direction of feild but i have read that 2 pi r is the circumference of circle which is equal to length of conductor
