1. 1/1 points All Submissions Notes Question: Walker4 22.P.039. A rectangular loop of 200 turns is  26  cm wide and 16 cm high. What is the  current in this loop if the maximum torque in a field of 0.45 T is  22  N ∙ m?     A 2. 1/1 points All Submissions Notes Question: Walker4 22.P.040. A single circular loop of radius  0.15  m carries a current of  3.3  A in a  magnetic field of 0.95 T. What is the maximum torque exerted on this  loop?    N ∙ m 3. 1/1 points All Submissions Notes Question: Walker4 22.P.045. Find the magnetic field  5.86  cm from a long, straight wire that carries a  current of  5.88  A.    T 4. 2/2 points All Submissions Notes Question: Walker4 22.P.048. Two power lines, each  200  m in length, run parallel to each other with a  separation of 35 cm. If the lines carry  parallel  currents of  120  A, what is the  magnitude and direction of the magnetic force each exerts on the other?  magnitude    N direction   5. 4/4 points All Submissions Notes Question: Walker4 22.P.050. Consider the long, straight, current-carrying wires shown in the figure. One  wire carries a current of  5.8  A in the  negative   y  direction; the other wire  carries a current of 4.5 A in the positive  x  direction.

(a) At which of the two points,  A  or  B , do you expect the magnitude of the  net magnetic field to be greater?  point  A  point  B      same at  A  and  B Explain.    (b) Calculate the magnitude of the net magnetic field at points  A  and  B . point  A      T point  B    T 6. 1/1 points All Submissions Notes Question: Walker4 22.P.058. A solenoid that is 75 cm long produces a magnetic field of  1.7  T within its  core when it carries a current of  7.8  A. How many turns of wire are  contained in this solenoid?   7. –/1 points Notes Question: Walker4 22.P.059. The maximum current in a superconducting solenoid can be as large
