Question
Imagine an x-y-z Cartesian coordinate system in space. A straight stream of protons passes through this space along the +y-axis (x=0, z=0). What is the direction of the magnetic field at a point on the -x axis?
ANSWER: along postive z axis
If an electron goes through this region having a velocity (-v,0,0), what would be the direction of its deflection?
ANSWER: along negative y axis
SOLVE THIS: If the protons pass through the point(0,0,0) at a rate of 5.7e+10 s-1, what is the magnitude of the magnetic field generated by the beam at point (0,0,-2.7)(unit:m)?
____ T
Explanation / Answer
I = f*e = 5.7e10*1.6e-19 = 9.12e-9 ............
B = uo*I/(2*pi*r) = (4*3.14e-7*9.12e-9)/(2*3.14*2.7) =
6.76e-16 T <---answer
