What to make "an electron moving in a magnetic field"?

Question

As you all have saw the code of gravity, where a ball goes downward. And formula of gravity field is F = mg.

Same for magnetic field formula is,
F= e(v x B)

F = Force on electron
e = charge of electron
v = velocity of an electron
B = Magnetic field intensity
