Read off radius
Radius
When flying through the magnetic field of the Helmholtz coils the electrons get
not deflected.
deflected.
The trajectory of the electrons in the magnetic field is
circular
parabolic
linear
The higher the acceleration voltage $V_{\text a}$, ...
the smaller the radius.
the larger the radius.
The higher the current $I$, ...
the smaller the radius.
the larger the radius.
The formula for the radius of the circular orbit is:
$r=\frac{e\cdot v_0}{m_e\cdot B}$
$r=\frac{m_e\cdot v_0}{e\cdot B}$
$r=\frac{m_e\cdot B}{e\cdot v_0}$
