Question
An infinitely long wire is bent as shown in the figure. The current is i. It consists of three segments, AB, BCD. and DE. AB and DE are parallel and both infinite in length. BCD is a semi-circular arc, with radius OB = OC = OD = r. The following questions are concerned with the magnetic field vector, B, at O. What is the direction of B at O due to the entire wire, ABCDE? 1. in the positive y direction 2. in the negative y direction 3. in the positive x direction 4. in the positive z direction 5. in the negative x direction 6. in quadrant III 7. in quadrant II 8. in quadrant IV 9. in the negative z directionExplanation / Answer
in _ve Y direction option 2
