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? along positive z axis (i got this correct)
If an electron goes through this region having a velocity (-v,0,0), what would be the direction of its deflection? along negative y axis (i got this correct)
If the protons pass through the point(0,0,0) at a rate of 6.3e+10 s-1, what is the magnitude of the magnetic field generated by the beam at point (0,0,-2.2)(unit:m)? T
Explanation / Answer
B = (uo*q*v)/(4*pi*r^2)
B = (4*3.14e-7*1.6e-19*6.3e10)/(4*3.14*2.2*2.2)
B = 2.08*10^-16 T <----answer
