- A current i = 2.0 A flows in a long straight wire and in a circular loop as indicated in the figure below. If the distance a = 3.0 cm, what is the magnitude of the magnetic field at point P at the center of the loop? Express your answer to the nearest µT.Each of two long straight parallel wires 8 cm apart carries a current of 125 A. The figure shows a cross section, with the wires running perpendicular to the page and point P lying on the perpendicular bisector of the line between the wires. Find the magnitude and direction of the magnetic field at P when the current in the left-hand wire is out of the page and the current in the right-hand wire is into the page. What is the magnitude of B? What is the value of By? What is the value of Bz?A thin conducting wire is bent into the shape shown in the figure. The circular portion of the wire has radius 26.0 cm. The wire is in the plane of the screen and carries a current 3.30 A. What is the magnetic field at the center of the loop? (Give the magnitude in µT.)
