Homework Statement
Two long parallel wires 20 cm apart carry currents of 5.0 A and 8.0 A in the same direction. Is there any point between the two wires where the magnetic field is zero.
Homework Equations
B=muI1I2/(2pir)
The Attempt at a Solution
I set the two B equations equal to each other to solve for r, but am stuck on what to do once I set them equal to each other: B1=B2, muI1/2pir = muI2/2pir
