Lorentz Force equation: F=q(v×B) Electron moves through the magnetic field B accelerated by force F proportional to the component of velocity perpendicular to the field B and velocity v. Moves with constant kinetic energy and speed due to the fact that the magnetic field never does work on the particle since the always moves perpendicular to the force. Magnetic force: F=evB The radius of the arc can be through: (mv^2)/R=evB giving R=mv/eB The length of the circular arc is S and the deflection angle is found as sinθ=S/R For small θ, and large R, the arc length S will be approx L, giving sinθ=L/R=LeB/mv Giving θ=sin^(-1)〖 (cBL/p)〗 The displacement is found as: d=R-Rcosθ=mv/eB(1-cosθ)
