NOTE: A good way to check that the mercury lamp is
centered properly is to remove the axial iron core plug
(with the knurled silver knob) from one end of the elec-
tromagnet. Next, shine a light-emitting diode (LED)
flashlight through the hole and look between the poles
of the electromagnet to see that the light is shining on
the mercury lamp and that the lamp is centered.
Remember to replace the axial iron core plug
.
2. Measure the height of the center of the axial iron core plug as
shown in Figure 7 and record the height.
