Two long wires carrying current I1 and I2 in opposite directions pass through a closed path S as shown in the picture.
What are the values of ∫B⋅ds and ∫E⋅ds if:
ii) I1=1A and I2=0A?
Ampere's Law: ∫B⋅ds=μ0I
Faraday's Law: ∫E⋅ds=-dΦB/dt
The Attempt at a Solution
For i, ∫B⋅ds=μ0(I1-I2)=μ0(0)=0
For ii, ∫B⋅ds=μ0(I1)=μ0(1)=μ0
Is these correct? But I have no idea of finding ∫E⋅ds
