50 cm-long wire is carrying a current of 100 mA in +x-direction parallel to the round. The wire has a weight 0.01 N. There is a pre-existing magnetic field B i hat region so that the weight of the wire is balanced by the magnetic force BI n it. What would be the magnitude and direction of B ? (Assume conventional irection of current).
