A toroid is made of 2 000 turns of wire of radius 2.00 cm formed into a donut shape of inner radius 10.0 cm and outer radius 14.0 cm. When a 30.0-A current is present in the toroid, the magnetic field at a distance of 11.0 cm from the center of the toroid is
 a. 0.0857 T.
  b. 0.109 T.
  c. 0.120 T.
  d. 0.600 T.
  e. 0.685 T.

Question 2

 a. points radially away in the direction from the current element to the point in space. b. points radially in the direction from the point in space towards the current element.
  c. points in a direction parallel to the current element.
  d. points in a direction parallel to but opposite in direction to the current element.
