[bclement10]

A long solenoid (radius = 3.0 cm, 2 500 turns per meter) carries a current given by I = 0.30 sin(200 t) A, where t is measured in s. When t = 2.5 ms, what is the magnitude of the induced electric field at a point which is 4.0 cm from the axis of the solenoid?
 a. 9.3  10-3 V/m
  b. 8.0  10-3 V/m
  c. 6.7  10-3 V/m
  d. 5.3  10-3 V/m
  e. 1.9  10-3 V/m
