At each of the locations labeled by a letter, use the right hand rule to find the direction of the magnetic field at that location, due to the current in the ring. Location A -x -x Location B +x +x Location C -x -x Location D +x +x Location E +x +x Location F +x +x 2. 3/3 points Question: MI3 18.8.X.053 (a) A loop of wire carries a conventional current of 0.9 amperes. The radius of the loop is 0.09 m. Calculate the magnitude of the magnetic field at a distance of 0.33 m along the axis of the loop, from the center of the loop. B = 1.145e-7 1.14e-07 T (b) What would the magnitude of the magnetic field be at the same location if there were 100 loops of wire in a coil, instead of one loop? B = 1.145e-5 1.14e-05 T Ch18 HW4 F2010 (Homework) Stefan Coreth PY 208, section 002M, Fall 2010 Instructor: Laura I. Clarke Web Assign The due date for this assignment is past.
