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. Now bring N pole of second ba..

The Bohr's atom model pictures the electrons to revolve around stationary heavy nucleus of change +ze. The moving electron constitutes a current where e is the electronic charge and T the time period of revolution. Also where v is its orbital velocity and the radius of the orbit. The..

08. - In the Bohr model of the hydrogen atom the electron revolves around the nucleus in a path of radius 5.1 x 10 - 1 1 m at a frequency of 6.8 x 10 1 5 revolution per second. What is the value of magnetic field at the center of the orbi..

It could not explain the line spectrum of multi electron atoms. This model failed to explain the effect of magnetic field on the spectra of atoms (Zeeman effect). The effect of electric field on the spectra could not be explained by Bohr's model (Stark effect)...

The direction of the magnetic field around a current carrying conductor can be explained by a simple rule known as Maxwell's right hand grip rule. If we hold the current carrying wire in our right hand in such a way that the thumb is stretched along the direction of the current,..

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..

>Neutral fragments are not deflected by the magnetic field and are lost on the walls of the instrument. Positively charged fragments, however, are sorted by the mass spectrometer onto a detector, which records them as peaks. Since the number of charges 'z', is usually 1, the peaks represe..
