particles like protons, nuclei, electrons, …) is of course influenced by the magnetic fields. This influence is given simply by the well-known Lorentz equation. The member with electric field in this equation could be neglected, because there is no evidence for large-scale electric fields in the Galaxy. For the acceleration $\vec a$ we get then: $$\vec a = \frac{q}{m} (\vec v \times \vec B),$$ where $q$ is the charge of particle, $m$ is its relativistic mass, $v$ its velocity[^8] and $B$ is the magnetic field strength.

Taking $\vec B$ as constant in suitable small volumes the trajectory of a particle is followed and the resulting deflection is examined.

“Antiparticle tracing” method and recent works
----------------------------------------------

Some computer simulations in the UHECR range were treated for this purposes recently and the effects especially on the changes in spatial distribution were studied.

The method of “antiparticle tracing” is used in all these models. The particle carrying the opposite charge starts its propagation on the position of the Earth in the Galaxy. Its initial velocity vector has spherical coordinates $\sim c, b, l$, where $c$ is the velocity of the light and $b$ and $l$ are
