You are given a pair of Helmholtz coils, as pictured below, and given the fact that the coils have finite thickness you performed 4 measurements of the coils' diameter, 2 measurements on the inside of the coils and 2 on the outside, as shown in the picture below

m: - -"' 6 and obtained the following results: D1 : 28.2cm, D2 : 28cm, D3 : 28.4cm, and D4 : 26.6cm. What is the mean radius and standard error of the mean ofthe coil radius? R=_/ :Exm You run a current of I = 2.1 A through each coil. Total number of loops in each is 130. Calculate the magnetic field produced in the center of the space between the coils, assuming the spacing between the coils is equal to the radius of the coils. Note: This condition may not be satisfied exactly in the lab. Your Lab 048 manual includes information that may be useful in this calculation. B=Ex mT
