6.4 Preliminary Assignment 1) A voltage is varied in a primary solenoid with 2900 + 100 turns of coil. The length of the solenoid is (0.121+0.002)m and has a resistance of (72.9 +0.7) $2. The voltage as a function of time is listed in the following table: Time Voltage in the (ms) Primary Coil (V) 2.65 -3.096 3.14 -1.859 3.67 -0.304 4.23 +1.277 4.81 +2.903 5.42 +4.500 A) Use some graph paper to plot the voltage vs. the time. B) Calculate the slope of the line from the graph in part A. C) Divide the slope in Part B by the resistance of the primary solenoid to obtain AT/ (with uncertainty). 2) A secondary solenoid with a radius of (1.95+0.01) x10 2m is inside the primary solenoid from Problem 1. This secondary solenoid has a total of 350 turns. Determine the EMF induced in the secondary solenoid (with uncertainty) using Equation (6.5).
