The Relationship Between Magnetism and Electricity by Bidisha Essay

The Relationship Between Magnetism and Electricity by Bidisha Mukherjee - Essay Example 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 t he south pole, coexist, and there can be no existence of one without the other.
