Relevance. Rating Newest Oldest. Best Answer: In a generator, residual magnetism, also known as 'remanence' or remanent flux, is due to the hysteresis of the magnetic material in the core. When the current is removed, the magnetic flux often remains at some non-zero value. This is a characteristic phenomenon of ferromagnetic materials.
10 hilariously insightful foreign words. The term magnetism describes the force of repulsion and attraction between different substances, such as iron and other metals. In magnetism, the motion of charged particles is ultimately responsible for the attraction or repulsion between substances. Objects that are attracted to each other illustrate the magnetic principles of ferromagnetism and paramagnetism, while diamagnetism describes the repulsion of magnetic fields.
