Problem 5 (need to show coordinate system used in the calculation. Draw a clear picture (and labels) 10 points A loop shaped in the form of a square, with sides of length 2L, carries current I. a) Using Biot-Savart, find the magnitude of the magnetic field from the loop at a distance R from the center of the loop along a line that is perpendicular to the loop and goes through the center of the loop, as a function of i and L. (Use any variable or symbol stated above along with the following as necessary: Mo.) b) Find the magnetic moment of the loop
