Recently, I have become fascinated with the many ways in which racism is being used in our society today. No, not the actual instances of racism, but rather how the word or accusation of racism is thrown around by our politicians. Also, it seems as if it is mostly used by the liberals. Originally, racism was used by politicians to mean that same thing as its literal definition: hating someone because of their race. But that has all changed; at least 95 percent of the time racism is now used to mean something else.
Electric fish produce their electrical fields from a specialized structure called an electric organ. This is made up of modified muscle or nerve cells, which became specialized for producing bioelectric fields stronger than those that normal nerves or muscles produce. Typically this organ is located in the tail of the electric fish. The electrical output of the organ is called the electric organ discharge (EOD).
Sources of electric field. Causes and description. Electric fields are caused by electric charges or varying magnetic fields. The former effect is described by Gauss's law, the latter by Faraday's law of induction, which together are enough to define the behavior of the electric field as a function of charge repartition and magnetic field.
