Spontaneous magnetization is the appearance of an ordered spin state (magnetization) at zero applied magnetic field in a ferromagnetic or ferrimagnetic material below acritical point called the Curie temperature or TC. Heated to temperatures above TC, ferromagnetic materials become paramagnetic and their
Distributions systems represent an important parts in the electrical grids and for this reasons the electrical generation & distribution companies delicate approximately 40% of the capital investment for distribution systems while the remaining is given to generation and transmission (40% generation &
Very basic question which an electrical student or professional may be asked is what is electric current and electric charge. The electric current is actually the flow of electric charge from one point to other point of the conductor or wire or cable.
In a paramagnetic material the magnetization of the material is (approximately) directly proportional to an applied magnetic field. However, if the material is heated, this proportionality is reduced; for a fixed value of the field, the magnetization is (approximately) inversely proportional to
FARADAY’S LAW OF ELECTROMAGNETIC INDUCTION According to the Faraday’s law of electromagnetic induction, emf gets induced in the rotor. As the rotor circuit is closed one so, the current starts flowing in the rotor. This currents called the rotor current. This rotor
Transformer is very simple and basic part of electrical system and considered most efficient of electrical components of machines. If we consider experimental models which are using superconducting windings then we may talk about achieving the the performance of 99.75 percent as
