A Helmholtz coil is used to generate a uniform magnetic field. Suppose the Helmholtz coil consists of two sets of coaxial wire loops with 16.0 turns of radius R = 89.5 cm, which are separated by R, and each coil carries a current of 0.141 A flowing in the same direction. Calculate the magnitude and the direction of magnetic field in the center between the coils.
