Position of particle in a magnetic field

Click For Summary
SUMMARY

The discussion centers on calculating the position of a charged particle in a magnetic field as a function of time, specifically for a particle with mass m and charge q, moving with an initial velocity of (Vx, 0, 0) in a magnetic field represented as (0, 0, Bz). The Lorentz force equation, F = q(V x B), is utilized to derive the acceleration components, Ax = qVyBz and Ay = -qVxBz. The participant, Gareth, presents equations for X(t) and Y(t) but seeks further guidance on progressing from these equations.

Homework Statement



I am wanting to get position (x and y) of a particle moving in a magnetic field as a function of time.
So, we have a particle of mass m, charge q, velocity (Vx,0,0) moving in a magnetic field (o,o, Bz) starting at t=0 as (0,0,0), what is X(t) and Y(t).

Homework Equations



Lorentz Force F=q(VxB)
F=Ma



The Attempt at a Solution



Ax = q Vy Bz
Ay = - q Vx Bz

follows that

X(y,t) = (q.Y.Bz + A1)t + A2
Y(x,t) = (-q.X.Bz +A3)t + A4

but not sure where to go from here


cheers

Gareth
