Figure shows a pair of wires AB and CD in four different configurations carrying the same current i . The force acting on the wire AB in each configuration is

Options

  1. Azero
  2. Bsame
  3. Cdifferent in magnitude & direction
  4. Ddifferent in direction only

Correct answer

B. same

Step-by-step solution

Since the projection of AB on CD is the same and both carry the same current so each pair experiences the same force.
