The Relationship Between Magnetism and Electricity by Bidisha Mukherjee - Essay Example

Physics and Earth Sciences Article Summary 19 January The relationship between electri and magnetism The article by Bidisha Mukherjee, “TheRelationship Between Magnetism and Electricity”, discusses the link between electric and magnetic fields, and the way one can be produced and effected by the other. It states that a changing electric field, or electric field in motion, called electricity, produces a magnetic field. Similarly, a changing magnetic field produces and effects an electric current.

However, if a static charge is placed in an electric field, or if the magnetic field is made static, one field would neither produce nor effect the other field. This phenomenon has been put to use in many devise which work on the principle of changing fields. The basic reason for the interplay of fields is that in an atom, a negative charge, the electron, is spinning around a positive core, the nucleus, producing a loop of electric field as a result of this motion. This electric field in turn produces a magnetic field.

The article then proceeds to describe the concept of a field, and the scientists who have worked on this relationship between the two fields. It then lists several principles or characteristics of this interchange of fields. It focuses mainly on the need for movement of the particles if a field is to be induced by another field. It also states that both the poles of a magnet, the north and the south pole, coexist, and there can be no existence of one without the other. This article is related to the course studied in this week as it discusses at length the relationship between an electric and a magnetic field, otherwise also known as electromagnetism.

It gives the underlying basis of this phenomenon, which is very important in understanding the reason behind and application of this relationship. It lists the basic and fundamental principles of this relationship, explaining each principle. It also explains the importance of motion related to this inter-conversion and production of the two fields. This is an important and interesting article to read on the pertinent topic. The article is written in a very easy language and manner. This makes it not only interesting but easily comprehensible, so that, although it is related to scientific facts and theory, it can easily be understood by an average reader of science.

It includes the names of scientists who were associated with the investigation of this phenomenon. It mentions the name of Hans Christian Oersted, a name that is often omitted by other texts on the subject, and gives the due credit of the discovery of this phenomenon to him, instead of Michael Faraday, as is often the case with other articles. It concisely explains the basis and the relevance of the important factors related to this phenomenon, making it scientifically authentic and worthwhile.

Therefore, this article is a must read on the pertinent subject. Works Cited Mukherjee, Bidisha. “The Relationship between Magnetism and Electricity.” Electricity. Buzzle.com, n.d. Web. 19 Jan. 2012. http://www.buzzle.com/articles/the-relationship-between-magnetism-and-electricity.html
