    Explanation:

    τ = Maximum torque of the loop = 9 mN

    N = Number of turns in the loop = 50

    a = side of the loop = 15 cm = 0.15 m

    A = Area of the loop = a² = 0.15² = 0.0225 m²

    B = magnitude of magnetic field = 0.800 T

    i = magnitude of current in the loop

    Maximum torque of the loop is given as

    τ = N B i A

    Inserting the values

    9 = (50) (0.8) (0.0225) i

    i = 10 A
