%X Downward continuation of magnetic field allows to enhance the resolution. Among the available techniques, iteration method for downward continuation of magnetic anomaly has better accuracy and a larger continuation depth. Firstly, the principle of the iteration method is presented, the characteristic of the method is analyzed. The downward continuation computation for model and practical data with noise of different variance is performed by means of iteration method. The accuracy, reliability and stability of iteration method are evaluated based on comparison and analysis of downward continuation results with real magnetic anomaly data. Practicability of iteration method is enhanced.
