I'm not sure where to place this, so please forgive me.
As you know, an electron experiences a force of F = qVxB in a magnetic field and equating this to centripetral force, we can find the radius of the electron's path to be R = mv/qB Ok, that's simple enough.
Now, I want to model an electron via 3D graphing in a magnetic field. For this, I need to model every part of its trajectory. This is proving tricky.
Say we have:
Bx = 0
By = 0
Bz = 1 micro tesla
The initial electron is coming in at
Vx = 0
Vy = 1.5e8 m/s
Vz = 0
The cross product is
Fx = q(VyBz - ByVz)
Fy = q(VxBz - VzBx)
Fz = q(VxBy - VyBx)
Now the acceleration is just a = F / m
However, For ax I'm getting 4.23e13 m/s^2! which is a wee bit high. Ok, just plain wrong. How would you generate an animation of an electon in a magnetic field? I would like to extend it so the magnetic field osccilates and varies with amplitude versus time.
