SUMMARY
The discussion centers on determining the direction of the magnetic field (B) using the Right Hand Rule in the context of two currents, I1 and I2. The magnetic field expression for the region R > F is given as (μ/2πR)(I2 - I1). To apply the Right Hand Rule correctly, the thumb should point in the direction of I1. The resultant direction of the magnetic field depends on the relative magnitudes of I1 and I2; if I2 is greater than I1, the direction of B will follow the chosen orientation, otherwise, it will reverse. Without specific values for the currents, the direction cannot be definitively determined.
