Magnetic Force Between Two Parallel Current Carrying Wires, Physics & Electromagnetism

This physics video tutorial explains how to calculate the magnetic force between two parallel current carrying wires using a formula derive from the equation of the magnetic force on a current carrying conductor and another formula which relates the magnetic field of a wire. This video on electromagnetism contains many examples and practice problems for you to work on.

What keeps you so motivated to learn and know all this stuff? I just finished organic chem and all your videos helped me through tough times. I know for sure these new physics videos you are uploading will help me next year when i take the course. But just wondering, are you just genuinely interested in the science courses because it it seems you are self-taught and are able to teach others in such a simple and understandable way!!

[ada]

hey, so i used your videos for my math lessons last year, and i'm pretty sure i used to fall asleep and the videos would still be playing, so ever since then i always think of 'sleep' when i watch your videos loool! thank you for all the work you do though!! you are a lifesaver!

[sangamxghimire]

You should change the name of channel because you teach whole Science ( Physics, Chemistry & Mathematics)

[balajothiadithya]

Dude you are my hero.Thanks for making Physics so interesting.

[annabellewagner]

why did i just happen to stumble upon this channel only two weeks before the last day of school 🤦🏼‍♀️

When you do the right hand rule and curve your fingers around the wire, can you thing of the direction of the fingers as the North-South direction of the field lines? Which would mean that if you have two magnetic North-South lines created from two currents from two different wires traveling at opposite directions, that's why the magnetic forces felt between the wires are repelling?

Thx for helping us all prepare for our various papers, Great Channel

[mattphorwich]

Youre the best! Great videos for learning the steps and how to apply them.

[unitedforever]

Thank you very much for the videos sir.

I just saw my result and it was fabulous 💖💖💖

[flopateernasef]

that was awesome! but i have a question
what will the equation be if they have diff lengths?

[nathanieltalker]

Does voltage in a wire effect the size of a magnetic or electrical field, thus effecting a parallel wire??

[shuewingtam]

You said 'right hand rule. Correct saying is left hand rule since magnetic field going in the screen. Anyway, direction of force shown is correct.

Exercise

1. Two straight long parallel wires, separated by a distance of 1.0 m, carry a current of 4.00 A each. A third wire is arranged perpendicular to the two parallel wires. If the magnetic field at a point equidistant from all the wires is zero, find the current in the third wire. guys please help me for tomorrow

[mathmachine]

What happens if they're of different length?
Newton's third law says that the force of wire 1 onto wire 2 has to be equal and opposite to the force of wire 2 onto wire 1.
Doesn't that necessitate that µ0*I1*I2*L2/(2πR) has to equal µ0*I2*I1*L1/(2πR), thus that L1 has to equal L2?

[sameerrai]

What to do if we have different lengths wire?

[el_witcher]

3:53 why does he take the B from the wire on the left? The wire on the right also produces a magnetic field. Why can we not use it in the equation for the force? We have its current and could use that R=2. Why can't we do this?

[hellmuth]

Normal people: "length"
Organic Chemistry Tutor: "lenf"

[TomiBorchert]

yesyesyes but how much the current changes??? example in transformers, current produces mfield, mfield makes current run in the second wiring. The change in amperes. the relatioship. Reduction, Boost, no affect? we assume the second wire has no voltage, no current. To produce current of 1amp, how much current/voltage do we need in the first wire. Let's assume they are like within 1cm.

[nomoregoodlife]

could someone please explain to me what an interaction would look like between two lines of opposing flow. Either because the energy is really high or because the lines are very close? Would it never spark because there is no attraction?

thank you c:

For question 1 I keep getting 5x10^-4N
