Discuss the applications of MR fluids and how they are made. Suggestion: search NASA's website. One example you'll find there, the Dong Ting Lake bridge in China (see below), utilizes MR motion dampers to counteract wind. Another example is "liquid body armor," for which a search of the web will reveal several interesting applications, as well as some diagrams showing how these fluids work. Address some of the following in your posts and responses: What are the sources of the magnetic fields for these fluids? What are the compositions of these fluids? How many applications of these fluids can you discover? Be sure to cite your sources. Wikipedia, while useful, is not a primary resource, and you should not cite it. To earn the maximum number of points for this discussion, you must: •Post your response of at least 150 words in your own discussion thread by day 4 of the module.
Figure (a) below gives the magnitude E(x) of the electric fields that have been set up by a battery along aresistive rod of length L = 9.02 mm (Fig. belowb). The vertical scale is set by Es =4.02 ×103 V/m.
