Laws of Magnetism - To find out about laws of magnetism you can perform the following simple experiment. Suspend a bar magnet as shown in figure, so that it can freely rotate. Allow it to come to rest. You will notice that it remains in north-south direction...

In order to study the working of an electrolytic cell and the phenomena of electrolysis it is important to know the working of a galvanic or a voltaic cell that generates electrical energy from its chemical reactio..

In order to study the working of an electrolytic cell and the phenomena of electrolysis it is important to know the working of a galvanic or a voltaic cell that generates electrical energy from its chemical reaction. In a simple voltaic cell a zinc plate and a copper plate are i..

Newton's Law of Gravitation and Einstein's Theory of Relativity were remarkable inventions in the world of Physics that changed the world. Physics is essentially a part and parcel of our everyday life and an understanding of its basic concepts is important to study advanced concepts like Electric ..

Michael Faraday discovered that a specimen of bismuth was repelled by a strong magnet. Diamagnetism occurs in all materials. These materials are those in which individual atoms do not possess any net magnetic moment. [Their orbital and spin magnetic moment add vectoria..

Surface chemistry is the study of processes that occur at the interface of two bulk phases. The bulk phases can be of the type solid-gas, solid-liquid, liquid-gas and liquid-liquid. There is no interface between gases because of their complete miscibility. The bulk phase can be solutions or pure co..

The principle states that the electron in an atom are so arranged that they occupy orbitals in the order of their increasing energy. Since the energy of a 'n' orbital in the absence of any magnetic field depends on the 'n' and 'l' quantum number values, the order of filling orbitals with..

A simple D.C. generator consists of a rectangular coil ABCD which can be rotated rapidly between the poles N and S of a strong horse-shoe type magnet M. The generator coil is made of a large number of turns of insulated copper wire. The two ends of the coil are connected to the ..
