1. Asuming that the distance between the rows is 1.25 cm, calculate how much the field should decrease between the first and second rows, assuming that the starting value is 3.66 G. (Remember that the magnetic field follows an inverse square rule.) Please show work.

Record your answer here: _________________________ This calculated number should be similar to the 2^nd value of the magnetic field (the measured number) you recorded in the table in question 6.
