arrow. Repeat the action of pivoting and touching with
the front lead until the potential reading in a given
direction is highest. Draw a new arrow. Repeat the
action of putting the ground lead at the tip (head) of
each new arrow and finding the direction in which the
potential difference is highest. Eventually , the arrows
drawn in this manner will form a field line. Return to the dipole and select a new point at which to place the
voltmeter's ground lead. Again probe with the other lead
until the direction of highest potential difference is
found. Draw an arrow from the ground lead to the other
lead, and repeat the process until a new field line is
drawn. Continue selecting new points and drawing field
lines around the original dipole (see Figure 6).
