1 Four WiresFour long #10 copper wires set up are parallel to each other. (#10 wire has a diameter of 2.588 mm and can carry currentsof more than 50 A.) Their cross sections form a square that is d = 10 cm on a side. A current of I = 20 A is sent thougheach wire in the direction shown in the figure.(a) What is the magnitude and direction of the magnetic field B at point P, the center of the square?(b) What is the total force on a 2m segment of the lower left wire? Give both the magnitude and the direction.

Chapter 28, Problem 020 An electron is accelerated from rest through potential difference V and then enters a region of uniform magnetic field, where it undergoes uniform circular motion. The figure gives the radius r of that motion versus V¹/2. The vertical axis scale is set by rs= 4.0 mm, and the horizontal axis scale is set by V¹/2= 32.9 V¹/2. What is the magnitude of the magnetic field? r (mm) VI/2 V¹/2 (¹/2)
One long wire lies along an x axis and carries a current of 38 A in the positive x direction. A second long wire is perpendicular to the xy plane, passes through the point (0, 4.3 m, 0), and carries a current of 64 A in the positive z direction. What is the magnitude of the resulting magnetic field at the point (0, 0.60 m, 0)? Number i Units
