1. a. Write down an expression that represents the mathematical form of Biot-Savart law for a coil of wire carrying current I (when the length of the coil is small compared to the coil's radius). i. Express the equation for the limiting case where x approaches zero. ii. Express the equation for the limiting case where x approaches infinity (very large). b. Suppose you are making a log-log plot of magnetic field vs distance from the center of the solenoid (log of the magnetic field goes to the y-axis and the log of the distance from the center of the solenoid on the horizontal axis). Determine a theoretical (i) (ii) slope of the graph for the limiting case where x approaches zero. slope of the graph for the limiting case where x is very large.
