Use the law of Biot & Savart to calculate the magnetic field of an infinite straight wire 47 The law of Biot and Savart is dB 190, dlxi where Ho = 47 x 10-7T m/A is the magnetic permeability, di is an infinitesimal piece of conductor and Fis the position vector pointing from di to the observation point. We will use this equation to calculate the magnetic field from a current carrying wire that is infinitely long. For the following questions refer to this figure: 'L 7- I dx X (1) In terms of dar and the direction vector what is dē? 1 2 (2) What is the magnitude of al x 71 in terms of de and a trigonometric function of o? X
