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 . The equal current flowing in the two conductors is :
30A in the same direction.
30A in the opposite direction.
60A in the opposite direction.
300A in the opposite direction.
As so currents are in the opposite direction
Hence the correct option is 2
