Two long straight parallel wires carry currents I1 and I2 respectively, in the same direction (as shown). The distance between the wires is R. The magnetic field at the centre of the two wires will

(1) `(mu_(0)(I_(1)-I_(2)))/(piR)` into the plane of paper (If `I_(1) gt I_(2)`)
(2) `(mu_(0)(I_(2)-I_(1)))/(piR)` out of the plane of paper (if `I_(2) gt I_(1)`)
(3) `(mu_(0)(I_(1)-I_(2)))/(piR^(2))` out of the plane of paper (if `I_(2) gt I_(1)`)
