The magnetization m as a function of magnetic field h for various temperatures is numerically obtained for the one-dimensional random-bond Ising model with each bond energy either $+J$ or -J with equal probability. For high temperatures (kT/J>~0.6) the results obtained agree with those of Landau and Blume. We have obtained m vs h for low temperatures as a numerical approach to the zero-temperature limit.
