Magnetism (10 of 13) Magnetic Force Due to Parallel Wires, Current Same Direction

Explains how to determine the direction of the force from parallel current carrying wires. If the currents in the wires are flowing in the same direction then there is a force of attraction between the two wires. If the currents in the wires are flowing in the opposite direction then there is a force of repulsion between the two wires.

Use the right hand rule to determine the direction of the force on the wire. Point your thumb in the direction of the direction of the current, point your fingers in in the direction of the magnetic field and the palm of your hand will "point" in the direction of the magnetic force on the wire.

Thankyou soo much, god bless you, I completed my 12 but I never get to know how to give ( direction of force ), ... You are a great teacher, I respect you sir from bottom of my heart 🙆🙆🙆 may your all wishes come true.

Thank you for explaining exactly how the fields on each side end up being into and out of the page! We totally glossed over that in class and I was so confused. You're incredible!

I am watching this now, interesting. This topic has been difficult to understand back then. Thanks for clarifying it for me. I got my Physics 2 final on Tuesday, wish me luck

I am in college, and these videos have made me understand 100x better than lectures. Thank you!

Was really hard to understand at school but this video made it so easy for me! Thank u so much😊

[adarshwilson]

Thanks a lot sir! Very informative, straight to the point, no bs and great narrative!

[brettrebuck]

All of these videos are incredible! I have had a horrible professor and these videos saved my grade!

Finally I anderstand
Thank you so much

[parfittelcano]

You're amazing! This is so clear :)

[louieluis]

so what is the effect when these forces get at each other? are they just boxing each other and find themselves knocked out afterwards?

Hello,
Two parallel wires 20cm apart carry currents in the same direction of 10A. What is the magnetic field halfway between them?
Can u help me please?
