1. Suppose the equilibrium separation of the rods is r = 4 mm, the rods are L = 15 cm long, and the current is I = 3.5 A. Use the equations in the theory section of this lab to: a) Calculate the magnetic field due to one rod at the location of the other. b) Calculate the magnetic force between the rods. c) Calculate the mass required to oppose the magnetic force. d) Calculate the required current to balance the weight of a 30 mg mass.
2. Using the same measurements of r and L as in question 1, a student measures a current of 5.9 A when she is balancing a 30 mg mass. a) What is her calculated value of μ0? b) What is the percent error between her result and the theoretical value?
