Disclaimer: I'm outside my area of expertise here.
Due to continuity constraints, when solving electromagnetic simulations with FEM, one uses edge based vector basis functions.
After solving, I would expect you to construct your solution field
$$\vec{H}(x) = \sum_i H_i \vec{N}_i(x)$$
or, element-wise
$$\vec{H}(x) = \sum_i H^e_i \vec{N}^e_i(x) \quad\forall x \...

Your particle is a rounded proton (mass m = 2e-27 kg instead of 1.672e-27 kg). The equation of motion is
$$
\dot x=v,~~~ m\dot v = q\,v\times B,
$$
where $B=(0,0,B_z)$ with $B_z=4T=4N/(m\,A)$ and $q=1e=1.602·10^{-19} C$, $C=A\,s$
This then gives for the acceleration
m=2e-27
e_charge = 1.6e-19
q=+1*e_charge
Bz = 4
ax = q/m*vy*Bz; ay = -q/m*vx*Bz; az = 0
For ...
