1. Hall probe Location on top or bottom
of the inside of the Window Frame
should detect field By up along the +y-axis
for the e-beam to experience a force
Fx along the +x-axis y
Electron beam into the slide
along +Z-axis
By up x
Fx along the
+x-axis
Summary:
if you place the hall probe it should detect field UP for the e-beam to bend along the +x axis.

2. Hall probe Location on left or right
of the inside of the Window Frame
should detect Bx field along the –x-axis
for the e-beam to experience a force
Fy up along the +Y-axis +y
Electron beam into the slide
along +z-axis
Bx along
-x-axis x
Fy along the
+y-axis
Summary:
if you place the hall probe it should detect field to the right for the e-beam to bend along the +y axis UP.
