[math]\displaystyle{ p_e = 14 \frac{MeV}{c} = 7.47 \cdot 10^{-21} \frac{m\cdot kg}{s} }[/math]

[math]\displaystyle{ B = \frac{p_e}{q_e \cdot R} }[/math]

[math]\displaystyle{ 1T=\frac{kg}{C\cdot s} }[/math], [math]\displaystyle{ q_e = 1.6\cdot 10^{-19} C }[/math]

[math]\displaystyle{ B(T) = \frac{4.67\cdot 10^{-2}}{R(m)} }[/math]
