The two anit-Helmholtz coils of a Z gradient coil are separated by 1 meter. If each coil produces a 50 Gauss magnetic field at its center, what is the magnitude of the gradient?

G = [B(1) - B(2)]/[Z(1) - Z(2)]

Where G = Gradient, B(n) = magnetic field at location n, and Z(n) = location n.

G = [50G - -50G)]/[1m (100cm/m)] = 1 G/cm
