The four wires in the figure are tilted at 20 with respect to the field direction. Each carries 4.5 and is 0.35 long. What is the magnitude and direction of the force on each wire?

  1. What are the dimensions of 20, 4.5 and 0.35? What is the field strength?

    Without a figure to show how the wires are arranged, I canot help you.

  2. I can't figure out how to post the image. The dimensions of the wire do not matter in this problem. And I am not given the B strength. Can I e-mail you a link to image?

  3. There are ways to post figures to a web address, and then add spaces between the letters or numbers in the address so that it will pass Jiskha screening software.

    The dimensions of the input numbers (meters, Amperes, degrees etc.) DO matter when calculating an answer (a force, in this case)

  4. Just got what you were asking:

    Each wire:
    20 degree angle
    I= 4.5 A
    l=.35m

  7. I was able to view your figure. Thank you for going to all that trouble. The magnitude of the forces on the wires shown are all the same, but a number cannot be assigned unless the value of B is known. The magnitude, in Newtons, will be
    F = B sin20*4.5 A* 0.35 m
    if B is in Tesla.

    The direction will be into the page for wires A and B, and out of the page for wires C and D.

    Those are the forces due to the external B field. There will also be forces of the wires on each other, but those are generally quite small. (Parallel wires with currents flowing in opposite directions repel each other, for example)
