Physics Ninja calculated the total force on a current loop placed in the magnetic field produced by a long wire. The force on each segment is considered.
When you are calculating the magnetic field on segment 1 you didn't consider the magnetic field due to current I2 on other segment (2,3&4) . Similar situation for other segment also.Is that negligible?
I have a question ? If we solve dlxB vectoral product we get opposite direction and same magnitude force for F2 and F4. And B opposite sign due to direction. So F2+F4 is not equal zero and F2+F4 same direction and same magnitude like F2+F4=2F2 ? Please answer my question.
Dude! Excellent presentation of content, except your audio is sub par. Gotta have better sound. Get that mic up in your sheeit! Also, overlapping two different diagrams can be confusing. The red and blue are two separate diagrams, so when you draw red circles and say the magnetic field gets weaker the further you get away from the wire, the circles are drawn on the first blue line, making it look like they are the same distance from the wire. It took a couple seconds to realize you're ignoring the blue diagram.
Right hand rule: wrap your fingers around a pencil, and point your thumb in the direction of the current. The way your hand curves around the pencil is the same way the magnetic field curls around the current
Thanks for your comment - I just checked the answer and i seem to have punched in the wrong numbers into my calculator. I'm horrible with numbers! The algebra works but my final answer is incorrect...by a factor of 2! If you do it correctly you should get 2*10^(-8). Sorry about that. Here's a link www.desmos.com/calculator/zn52svzmt2
I think i just wasted your time,I was asking about the "mu naught" it was the Vacuum Permeability constant. got it now. (BTW your complex and RC circuit video was fantastic I understand 100% of it, Thank you so much.)
Hi Jani, i'm not sure i understand the question. The total force (or Net Force) is acting on the loop. There is an equal but opposite force acting on the long wire thanks to Newton's third law.
