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…
Mobile Web Development
These days internet has ruled over the world. There are millions of websites that can be found in the internet. Some have a high loading capacity whereas some have low loading capacity. Even in mobile phones some websites load quite…
Fecal Incontinence
Fecal Incontinence is the inability to control the bowel or stool may leak from the rectum unexpectedly, sometimes while passing the gas. It describes the involuntary passage of stool from the rectum. Several factors influence fecal incontinence like; The ability…
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…
Diverticular Disease
A diverticular disease is a sac like out pouching of the lining of the bowel that extends through a defect in the muscle layer. In diverticular disease, bulging pouches (diverticula) in the GI wall push the mucosal lining through 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…
Biot-Savart’s Law
Jean-Baptiste Biot and Felix Savart jointly gave the Biot-Savart’s law in the year 1820. This is a rule or law which helps to calculate the magnitude of the magnetic field due to a current carrying conductor. Let ‘dl’ be a…
Theories Related To Acid and Base
There are different theories which help to determine whether a substance is an acid or base. The major and generally accepted theories are given below: 1. Arrhenius Theory According to Arrhenius theory, acid is a chemical substance which gives hydrogen…
