The divisions of a galvanometer are equally spaced to ensure accuracy and precision in measuring current. By having evenly spaced divisions, it allows for easier interpretation of the readings and reduces the margin of error in determining the current passing through the instrument. This uniform spacing also helps in calibrating the galvanometer for consistent and reliable measurements across different ranges of current.

It is the amount if current it takes for unit deflection in the given galvanometer. k = I/theta Where k is the figure of merit, I is the current supplied and Theta equals the number of divisions of deflection.

Contours for a gentle slope are spaced equally and far apart, the closer the contour lines the steeper the slope.
reduction factor is used to find earth's magnetic field and compare galvanometer constants
IG=Betanx. in this G is G.constant, I is current, Be is Megnetic field of earth, OK? or anything else?
