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.
