A 15-turn rectangular loop of wire of width 10 cm and length 20 cm has a current of 2.5 A flowing through it.
 
  Two sides of the loop are oriented parallel to a uniform magnetic field of strength 0.037 T, and the other two sides are perpendicular to the magnetic field.
  (a) What is the magnitude of the magnetic moment of the loop?
  (b) What torque does the magnetic field exert on the loop?
  What will be an ideal response?

Question 2

An L-shaped metal machine part is made of two equal-length segments that are perpendicular to each other and carry a 4.50-A current as shown in the figure.
 
  This part has a total mass of 3.80 kg and a total length of 3.00 m, and it is in an external 1.20-T magnetic field that is oriented perpendicular to the plane of the part, as shown. What is the magnitude of the NET magnetic force that the field exerts on the part?
 
  A) 8.10 N
  B) 11.5 N
  C) 16.2 N
  D) 22.9 N
  E) 32.4 N
