Action of the magnetic field

The ion follows a circular trajectory with a radius r so that the centrifugal force equilibrates the magnetic force 

For every value of 5, the ions with the same charge and the same momentum (mv) have a circular trajectory with a characteristic r value. Thus, the magnetic analyser selects the ions according to their momentum. However, taking into account the kinetic energy of the 

Orientation of the magnetic force on a moving ion. ions at the source outlet leads to 

The result is that ions with identical charge and mass are dispersed by a magnetic field according to their kinetic energy. In order to avoid this dispersion, which alters the mass resolution, the kinetic energy dispersion must be controlled. This is achieved with an electrostatic analyser.

W. Steubing found that the intensity of the fluorescence of iodine vapour is weakened between the poles of a powerful electromagnet. The result has nothing to do with the Zeeman effect, and has no connection with effects produced by admixture with gases, solvents, etc. It is produced by a direct action of the magnetic field on the electrons causing the band spectrum weakening the individual vibrations. 

The electron trajectories in a spectrometer are affected by magnetic fields. This is demonstrated with the help of Fig. 4.40 the formerly straight path of an electron with velocity v is deflected, under the action of the magnetic field B perpendicular to the trajectory, through a distance d given by... 

Let us consider now the effect of an inhomogeneous magnetic field on the particles in a free vessel and evaluate the conditions necessary for delivery of the carriers to the vessel wall in the area of effective action of the magnetic field with a characteristic length / (Figure 10.1). We consider the field level such as for... 

For further estimative calculations it is reasonable, as above, to use the average flow velocity U, with its value for different vessels shown in Table 10.2. Then the time of the carriers residence in the organ vessel in the absence of the field is T = l/ 7, where I is the area of active action of the magnetic field (Figure 10.1). 

As before, expressing through k, we find the condition of 100% carriers delivery to the vessel waU at the desired area in action of the magnetic field (here and below r is the hydrodynamic radius) ... 

In this symmetry (neglecting quadrupole interactions and the direct action of the magnetic field on the nucleus) the spin Hamiltonian takes the simple form of ... 

Vertical spikes of magnetic suspension appear as the result of action of the magnetic field, what causes the perturbation of the free surface of the polymer solution. Under the action of the electrical field, perturbations of the free surface become the sites of jetting directed upward. 

Let us restrict ourselves to the simplest case when a focal conic domain in the form of a TFCD is supposed to appear in a fiat cell of fixed thickness h from initially uniform stack of layers under the action of the magnetic field H applied across the cell. If the...
