Write out a system of equations to solve for all the currents in this network. Note, I'm NOT ASKING YOU TO SOLVE THEM!!; just be able to write them out. You need THREE junction equations, and enough loop equations to be able to solve the 3R www 들 R www ER с system. For my own sanity, when you write out loop equations PLEASE start at one of the two circled junctions. Circle on the diagram any sections you can simplify with effective resistances. You can assume the charge on the capacitor is Q, and that the system is in steady-state with respect to currents and charges. are there any currents here that are easy to solve for? What simplifications does the 2R www T-- 5R 2V

Ferromagnetism

Ferromagnetism is a mechanism by which some materials show magnetic properties. Iron and magnetite, an oxide of iron, are two naturally occurring materials that show the property of ferromagnetism. The word ferromagnetism is derived from the Latin name of iron, "Ferrum" as it was the first observed material to show such property. The property of ferromagnetism is shown by only a few substances such as iron, nickel, cobalt, and their alloys. Some transition metals and alloys of rare-earth metals also show ferromagnetism.
