(adsbygoogle = window.adsbygoogle || []).push({}); 1. Two-wire, long, straight parallel 10cm distant from each other, as shown in the chart.

Upper wire current issue I1 = 6A trend into the top level.

A. What are the strength of the current tendency I2 bottom wire, if the magnetic field equivalent at P equal Zero?

b. What is the equivalent magnetic field point? Q

C. What is the equivalent magnetic field point S?

2. not sure what to use

3. a) B[tot]=B1-B2=0

B1= μ0I1/ 2π*0.15

B2= μ0I2/ 2π*0.05

μ0I1/ 2π*0.15 = μ0 I2/ 2π*0.05

6/0.15= I2/0.05

0.3=0.15 I2

I2=2A

b) ??

c)B=√B1^2+B2^2 (?)

Thank you very much for your help.
