Problem

A once positively ionized xenon atom flew out from the center of a large cylindrical coil with velocity

v=7\,\mathrm{m\cdot s^{-1}}

and began to move through a homogeneous magnetic field, which is in a plane perpendicular to the magnetic lines of force. At a certain point the coil is disconnect from the source, thus its induction begins to decrease exponentially according to the following equation

B\!\left(t\right)=B_0\mathrm{e}^{-\Omega t}

, in which

B_0=1.1\cdot 10^{-4}\,\mathrm{T}

and

\Omega =600\,\mathrm{s^{-1}}

. What is the deviation from the initial direction after the atom is stabilized?
