A straight wire of length 70 cm carries a current of 50 A and makes an angle of 60 with a uniform magnetic field. If the force on the wire is 1.0 N what is the magnitude of B?
 a. 41 mT
  b. 33 mT
  c. 55 mT
  d. 87 mT
  e. 57 mT

Question 2

A segment of wire carries a current of 25 A along the x axis from x = -2.0 m to x = 0 and then along the z axis from z = 0 to z = 3.0m. In this region of space, the magnetic field is equal to 40 mT in the positive z direction. What is the magnitude of the force on this segment of wire?
 a. 1.0 N
  b. 5.0 N
  c. 2.0 N
