This work is based on the variational principle for magnetic field lines introduced in 1983 by Cary and Littlejohn. The action principles for magnetic field lines and for Hamiltonian mechanics are recalled to be analogous. It is shown that the first one can be rigorously proved from first princi...

Figure 3b gives the relative changes of the z-component magnetic field as a function of the external field strength measured at a fixed point z0=R3+h on the z axis for the structures with different material compositions. For the sole FM shell, the relative field change (blue) is nearly co...

Magnetic fields can be classified in electromagnetic field, pulse electromagnetic fields (PEMFs), static magnetic fields (SMFs) [105], alternating magnetic field (AMFs), or rotating magnetic fields (RMFs), SMFs, and PEMFs being the most used [104]. From biological point of view, as Peng ...
The strongest magnetic field, denoted Bo,therefore usually referred to inmagnetic resonanceas the main magnetic field or simply as ‘the magnet’, is measured inteslas(standard units of magnetic field strength). There are several designs of magnet, but at higher field strengths (>0.5 T) the ...

The integrated experiment used demonstrated that, in conjunction with the superconducting coil, greater homogeneity and a stronger magnetic field not only caused more even cathode ablation and improved its lifespan but also improved the performance of the MPDT (maximum thrust was 4 N at 150 kW, ...
