One long wire lies along an x axis and carries a current of 62 A in the positive x direction. A second long wire is perpendicular to the xy plane, passes through the point (0, 5.8 m, 0), and carries a current of 59 A in the positive z direction. What is the magnitude of the resulting magnetic field at the point (0, 1.8 m, 0)? Number i 0.00000295 Units
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)
