B) 45°
C) 60°
D) 90°
Correct Answer: D
Solution :
Magnetic meridian is a vertical N-S plane, the earth?s magnetic field \[({{B}_{H}})\] lies in it. (For more details see magnetism). To obtain neutral point at the centre of coil, magnetic field due to current and \[{{B}_{H}}\] must cancel each other. Hence plane of the coil and magnetic meridian must be perpendicular to each other as shownYou need to login to perform this action.
