Magnetic field generation

The equivalent of the spin-other-orbit operator in eq. (8.30) splits into two contributions, one involving the interaction of the electron spin with the magnetic field generated by the movement of the nuclei, and one describing the interaction of the nuclear spin with the magnetic field generated by the movement of the electrons. Only the latter survives in the Born-Oppenheimer approximation, and is normally called the Paramagnetic Spin-Orbit (PSO) operator. The operator is the one-electron part of... 

The magnetic field generated by a current passing through a coil of wire. 

The opposite question of how a magnetic field generates a current in a conductor is related to the foregoing discussion and is also of some interest to us. The first observation at the beginning of the century... 

Figure 10.3 The magnetic field generated by an RF pulse applies a torque to the bulk magnetization vector and drives it towards the transverse plane.

Figure 3 A schematic drawing of a typical ECR ion source. The ions and electrons are confined in the plasma by the magnetic field generated by the solenoid coils and the hexapole magnet.

For more appropriate element definitions. Equations (1) and (2) are extended to allow for the calculation of the magnetic field generated by a rectangular cross section element as ... 

The field fulfills the condition V = 0. This result is consistent with the fact that the curve Cj is a closed loop. The integral written above is identical to Biot-Savart law used to calculate the magnetic field generated by a current loop, provided this integral is multiplied by 4nl/c. 

As you can imagine, the size of the magnetic field generated by a single...

Subsequently Ya.B. s colleagues and students substantially advanced both the general theory of magnetic field generation and its practical applications to the Sun, galaxies, and other astrophysical objects. 

Ya.B. again extracted a precisely posed mathematical problem in the magnetic dynamo problem. From the standpoint of physics, the problem is one of the mechanism of magnetic field generation of the Sun or a star.
