Part F

Highly ionized iron atoms are found in the sun's outer atmosphere, or corona. One such ion has lost $13$ electrons and so has charge $+13e=+2\mathrm{.}08{10}^{-18}C.$ This ion experiences a magnetic force of $2\mathrm{.}30{10}^{-15}N$ when it moves at $7\mathrm{.}30{10}^3\frac{m}{s}$ in the $xz-$plane, $36\mathrm{.}9$ from the $+x-$axis and $53\mathrm{.}1$ from the $+z-$axis. The magnetic field is in the $+z-$direction. Find the magnitude of the magnetic field.

Express your answer with the appropriate units.
