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 ...
