The black arrows represent the Lorentz force which is exerted on a current-carrying conductor in the magnetic field. The problem of wave propagation has been solved and eddy currents and Lorentz forces have been calculated. Most of the current standard force fields except OPLS-AA use the Lorentz- Berthelot combination rule to estimate epsilon (ε ij) and sigma (σ ij) Van Der Waals parameters σ ij = (σ i + σ j)/2 ; ε ij = √ ε i ε j and is the only combination rule implemented in OpenMM. Then EM eld results are loaded into TEM3P for temperature and mechanical stress analysis. Because of the opposite Lorentz force of the imaging electrons impinging on the sample, the Lorentz contrast of a vortex core can be either black or white. Here, we will explore the behavior of electrons colliding with nano-magnetic disks. In most cases, a regime of large-scale oblique laminar-turbulent patterns is identified at the onset of transition, as in the case of pure shear flows.
