On Page 2 of the experiment file, plot a graph of magnetic field B vs . the current I through the solenoid. (Graph) 2.How is magnetic field related to the current through the solenoid? 3.Determine the equation of the best-fit line, including the y-intercept. Note the constants and their units. 4.For each of the measurements of Part II, calculate the number of turns per meter. Enter these values in the data table. (Table)5.On Page 3 of the experiment file, plot a graph of magnetic field Bvs.the turns per meter of the solenoid (n). (Graph)6.How is magnetic field related to the turns/meter of the solenoid? Physics with Computers
7.Determine the equation of the best-fit line to your graph. Note the constants 8. From Ampere’s law, it can be shown that the magnetic field Binside a long solenoid isBnI0where 0 isthepermeability constant. Do your results agree with this equation? Explain. 9. Assuming the equation in the previous question applies for your solenoid, calculate the value of 0using your graph of B vs. n . Physics with Computers
10. Look up the value of 0,thepermeability constant. Compare it to your experimental value. 11. Was your Slinky positioned along an east-west, north-south, or on some otheraxis? Will this have any effect on your readings? Physics with Computers
