Traveling magnetic fields

At the moment the technology is developed further to include different sources for electromagnetic stirring like traveling magnetic fields or to built facilities for use in strong magnetic fields.

Magnetic analyzer. A direction-focusing device that produces a magnetic field perpendicular to the direction of ion travel. The effect is to bring to a common focus all ions of a given momentum with the same mass-to-charge (m/z) ratio. 

The rotating magnetic field in the stator travels around the stator at what is called synchronous speed. By grouping stator coils together in what is called poles, the motor rotor can be designed to turn at a certain speed (revolutions per minute/rpm). On an induction motor the number of poles cannot be seen or counted without the drawings. 

In the magnetic-sector instrument (Figure 1.1), gas phase ions produced in the ion source by one of several different methods are accelerated from near rest (thermal energy) through a potential gradient (commonly kV). These ions travel through a vacuum chamber into a magnetic field at a... 

FIGURE A.9 An electromagnetic field oscillates in time and space. The magnetic field is perpendicular to the electric field. The length ot an arrow at any point represents the strength of the field at that point, and its orientation denotes its direction. Both fields are perpendicular to the direction of travel of the radiation. 

Fig. 2.6.1 Schematic of an experiment with remote detection. The basic steps are (a) the polarization of the sensor medium, (b) NMR or MRI encoding using rf pulses and magnetic field gradients and (c) signal detection. The NMR or MRI information travels between the locations (b) and (c).

The rate of radiocarbon formation in the upper atmosphere depends on a number of factors, which include the intensity of the incoming cosmic radiation, the activity of the sun, and the magnetic field of the earth (the latter affects the way cosmic rays travel). It can be safely stated, however, that radiocarbon is formed at a steady rate that averages just about 2.4 atoms of radiocarbon per second for every square centimeter of the earth s atmosphere outer surface.
