Question

7. Represent (draw) the magnetic flux lines, including their direction, of: a) a wire along the x axis, carrying a positive current in the positive direction of the x axis; b) a loop of current on the xy plane, centered in the origin and carrying a current along $\alpha_{\phi}$; c) a solenoid with axis along the z axis, centered in the origin and carrying a current in the $a_{\phi}$ direction; d) a toroid with axis along the z axis, centered in the origin and carrying a current with positive direction toward the $a_{\phi}$ direction. e) A bar magnet along the z-axis, centered in the origin; the South Pole is the part of the space with positive z and North Pole has negative z coordinates. Place a magnetic needle at a point P on the plane z = 0 and draw it as it would orient due to the presence of the bar magnet (indicate N and S of the magnetic needle).
