Abstract: A method includes pulsating a magnetic field at a first location associated with an external surface of a wall containing magnetic material. The method also includes measuring at least one characteristic of the pulsating magnetic field at a second location associated with the external surface of the wall. The at least one characteristic changes based on corrosion on an internal surface the wall between the first and second locations. The magnetic field could be pulsated by applying an AC signal to a conductive coil or by vibrating a magnet. The method could also include analyzing the at least one measured characteristic to identify an amount of the corrosion and/or a change in the amount of the corrosion. Use of the internal surface the wall could be modified based on the amount or change of the corrosion.

Abstract translation: 一种方法包括在与包含磁性材料的壁的外表面相关联的第一位置处脉动磁场。 该方法还包括在与壁的外表面相关联的第二位置处测量脉动磁场的至少一个特性。 至少一个特征基于第一和第二位置之间的壁上的内表面的腐蚀而改变。 可以通过向导电线圈施加AC信号或通过振动磁体来脉动磁场。 该方法还可以包括分析至少一个测量特征以识别腐蚀量和/或腐蚀量的变化。 内墙的使用可以根据腐蚀的数量或变化进行修改。 可以在多个第一位置处产生多个磁场，并且可以在多个第二位置处测量至少一个特性。
