Magnetic field

jks · February 11th, 2018, 07:44 PM

Can you use Ampere's Law and the example given here to solve this?

Hint: Normalize the magnetic fields produced by wire 1 and wire 2 at point O to 1 and note their directions. Add the vectors for the resultant magnitude $(\sqrt{2})$ and direction. Then determine the magnitude and direction of the current of wire 3 to cancel the resultant, keeping in mind the distance $(\sqrt{2} \ \text{m})$ from wire 3 to point O.
