Second-order equations 308 Chapter II. The use of the Dirac equation In physical problems 312 I. The free electron 312 2. An electron in a homogeneous magnetic field 316 3. Constants of the motion in ...

A method is presented for controlling the field-directed self-assembly of colloidal magnetic core–shell nanoparticles into three-dimensional (3D) crystalline superstructures with nanoscale feature ...

Magnetic fields are produced by electrical currents that are generated by various astrophysical objects. The study of magnetic fields seeks to understand their origin, as well as the acceleration ...

New compact semianalytical expressions of the scalar potential and magnetic fields produced by a radially polarized permanent magnet are described in this paper by using Coulombian approach. It uses ...

Graphene, having all atoms on its surface, is favorable to extend the functions by introducing the spin–orbit coupling and magnetism through proximity effect. Here, we report the tunable interfacial ...

This paper presents the real time control of Magnetic Levitation System using feedback linearization and online learning using Radial Basis function neural networks. It starts with the comparison ...
