It is noteworthy that this is one rare case where the sign of the particle charge does not change the direction of the force, unlike the lorentz force. The mechanism of the ponderomotive force can be easily understood by considering the motion of the charge in an oscillating electric field.
This pulling force can be qualitatively explained as the lorentz force produced by the interaction of the dielectric bound current with the incident light pulse [12]. Now let us examine the result from einstein lightquantum theory. The photon energy (frequency) is supposed to be the same no matter whether in vacuum or in a medium.
Since the ion-ion free paths (mfps) are much larger than the transition width of the shocks, generally, those shocks are excited by the electrostatic force 5,6 and/or lorentz force 7,8 instead of the coulomb collisions. Due to the difficulty in directly exploring the underlying microphysics of shock formation in the astrophysical conditions.
A pseudo-spectral method with an absorbing outer boundary is used to solve a set of time-dependent force-free equations. In this method, both electric and magnetic fields are expanded in terms of the vector spherical harmonic (vsh) functions in spherical geometry and the divergence-free state of the magnetic field is enforced analytically by a projection method.
The electrons do not experience a magnetic field locally, and therefore are not acted upon by a classical lorentz force. There is also the aharonov-casher effect: as neutral particles, neutrons do not exhibit what is traditionally regarded as the ab effect. However, neutrons have a magnetic moment and give rise to a companion topological.
In classical rta expression we get magnetic field independent parallel conductivity due to zero lorentz force but in field theoretical kubo expression, it decreases and increases with the magnetic field for scalar and dirac medium respectively due to landau quantization effect.
2) due to lorentz force, the twin-tungsten tig arc becomes a big arc, the arc is no longer axis-symmetry like single arc, the cross section of coupling arc is ellipse. 3) arc pressure of the twin-tungsten tig welding is very low even at high current, which is a very important merit.
We also find that the thermal force inside the cme is the internal driver of cme expansion while the lorentz force prevented the cme from expanding. It is noted that the centrifugal force due to poloidal motion decreased at the fastest rate, and the lorentz force decreased slightly faster than the thermal pressure force as the cme moved away.
When a species (ion or electron) with charge, q (coulomb), moves with velocity, v (meter/second), at a right angle to a magnetic field, b (tesla), the force, f l,b, that is one of two terms in the lorentz equation, acts on it in a direction sensitive to the sign of the charge and perpendicular to both v and b, with a cross product relationship.
I show that it is possible to formulate the relativity postulates in a way that does not lead to inconsistencies in the case of spacetimes whose short-distance structure is governed by an observer-.
F is the force acting on the particle (vector); v is velocity of particle ( vector); q is charge of particle (scalar).

Here, the authors show that the weak-field magnetoresistance (mr) in this hydrodynamic regime is caused by the modification of the flow pattern by the lorentz force. The resulting mr is positive and is controlled by the shear viscosity alone. This may help separate the viscous and the thermal contributions to the resistivity.

Abstract this chapter presents an experimental overview of collective flow phenomena in heavy-ion collisions in the incident energy regime from 100 amev to 160 agev. The characteristic features of various types of flow are described. The discussion of common dependences on the collision system and bombarding energy focuses on the different time scales of the underlying physics processes.
These control experiments strongly suggest that the detected negative mr originates from the interplay between the electric and magnetic fields instead of the anisotropy from the material itself, thus presenting a consolidate evidence of the chiral magnetic effect in the presence of e b fields.
Lorentz force can be used to induce motion in the electrically conducting fluids which might then lead to turbulence suppression and drag reduction. In this paper, drag reduction in turbulent channel flow via a transverse wave traveling along streamwise direction induced by lorentz force is investigated numerically by direct numerical simulation.
The non-helical current has a ballistic contribution (dominant in sufficiently clean samples) caused by asymmetric scattering of photoexcited carriers, and a side-jump contribution. Magneto-induced photocurrent is due to the lorentz force or due to intrinsic magnetic moment related to berry curvature.

The lorentz force is perpendicular to both the carrier velocity (electric current) and magnetic field. The charge carrier accumulation at the edge of the sample continues until it is eventually ceased by the electric field experienced in the opposite direction, which is considered to be the equilibrium state.

The force a magnetic field exerts on a charge q moving with velocity v is called the magnetic lorentz force.
Right-hand-rule used to determine the direction of the magnetic (lorentz) force. In the presence of a magnetic field, when a current is applied to a conductor, the electrons will experience a force at a right angle to the magnetic field, following the right-hand rule (or the physics gang sign, as we affectionately call it in my classroom).
Lorentz force is the fundamental force acting upon electric charge with certain velocity in a magnetic field. The right-hand rule is useful to visualize how the lorentz force works.
