- Homework Statement
- A current carrying coil has a spiral amount N1, length L and a current of I1 flows through it. A current of I2=2I1 flows through a cyclic current carrying wire, which has the coil's axis start as it's centre, has a radius of r=L/λ and is parallel to it. Find the spiral ratio N1/N2 where the magnitude B is equal to 0.

NOTE: Kμ is a constant equal to 10^-7

- Relevant Equations
- B1=Κμ4π(N1/L)I1 and B2=Κμ(4πI1/L)λN2

I used the two equations i listed by using [TEX]B1=B2[/TEX] and by doing that i ended up finding that [TEX]N1/N2=λ[/TEX].

However i am not sure if that's the correct answer as λ is just a variable and not an actual number. Do you think it has to be an actual number or is it not really necessary?
