Nepal is characterized by economic slowdown and inflationary outlook; the year 2009 would not be faring well for the global economy. It is projected that the global output will contract by 1.2 percentage point in 2008. The global slowdown is…
Magnetic Hysteresis
Let us consider a ferromagnetic material which is subjected to magnetizing field (H). The intensity of the magnetizing field (H) is gradually increased from 0. Then, the magnetic induction (B) also increases and becomes maximum (at point L in the…

Classification of Magnetic Materials
Magnetic moment of a bar magnet is defined as the product of the pole strength and the effective length of the magnet. If ‘m’ is the pole strength and ‘2l’ is the effective length, the magnetic moment (M) is M…
Bad Effects of Internet on Human Mind
These days, due to the rapid development in the field of Information Technology (IT), people have become very advanced. With the use of Internet and computers, the whole world has been compressed into the small screen of computers. People can…
Elements of Earth’s Magnetic Field
The magnetic field of the earth at any point on its surface is determined by using three physical quantities which are called elements of earth’s magnetic field. They are: Declination: Declination at a point of earth’s surface can be defined…
Ampere’s Circuital Law
Ampere’s circuital law was discovered by André-Marie Ampere in the year 1826 A.D. This law states that, “The line integral of magnetic field B along any closed path in free space is equal to the vacuum permeability (μo) times the…
Halo-alkanes
Halo-alkanes are one of the most widely used and important hydrocarbons. When one or more hydrogen atoms of hydrocarbon are replaced by halogen, then the hydrocarbon is called halo-alkane. It is represented by the general formula R-X, where R is…
