Two infinite straight wires run through an "infinite" solenoid a distance d = 2cm from the center of the solenoid. the wires carry a current of iwire = 5a in the direction drawn. the solenoid carries a current of isol = 1.5a in the direction drawn. the solenoid is wound using 500 turns of wire on a 13cm tube. (a)compute the magnetic field of the solenoid at point p, b~ sol. (b)compute the magnetic field of wire 1 at point p, b~ wire1. (c)compute the magnetic field of wire 2 at point p, b~ wire2. (d)compute the total magnetic field at point p.

In a unit cell of fcc structure, indicate the position of one of the tetrahedral interstitial sites by plotting the corresponding tetrahedron. do the same for one of the octahedral interstitial sites (in a separate fcc unit cell). mark the positions of all the tetrahedral and octahedral interstitial sites in the unit cells. how many equivalent tetrahedral sites and how many equivalent octahedral sites are contained in a fcc unit cell, respectively. what is the coordination number for a tetrahedral site and what is the coordination number for an octahedral site?
