Two long current carrying conductors are placed parallel to each other at a distance of 8 cm between them. The magnitude of magnetic field produced at mid-point between the two conductors due to current flowing in them is 30 μ T. The equal current flowing in the two conductors is:

1. 30 A in the same direction
2. 30 A in the opposite direction
3. 60 A in the opposite direction
4. 300 A in the opposite direction

Correct answer: 30 A in the opposite direction
