A beam of protons is directed in a straight line along the +z direction through a region of space in which there are crossed electric and magnetic fields. The electric field is 450 V/m in the -y direction and the protons move at a constant speed of 10^5 m/s.
1)What must be the magnitude of the magnetic field such that the beam of protons continues along its straight-line trajectory? (Express your answer using two significant figures.)
A proton is located at (0,0,0) at t=0 and has a velocity (0,v,0), where v is positive. The space is subject to magnetic field (0,0,B) where B is positive. As always, use CGS!
a) Draw a sketch of the closed-loop trajectory of the proton.
b) Will the magnitude of proton’s velocity change as a function time? Why? Prove it.
c) Calculate ?⃗ (?) -- the position of the proton as a function of time in Cartesian coordinates. The final solution should not depend on any new variable – only time, initial velocity v, mass of the proton m, proton charge +e, field B.
d) Write out the atomistic current density of the proton.e) Calculate the time-averaged current I due to the motion of the proton. Add it to the sketch.
f) Based on this current, what is the field (as always, direction and magnitude) in the center of proton’s trajectory. Do not solve the integral, just give and draw the solution.
