A) greater than at Q
B) same as at Q
C) less than at Q
D) greater or less than at Q, depending upon the strength of current
Correct Answer: B
Solution :
Let XY be a straight conductor carrying current \[i\]in the direction from X to Y. Magnetic field at P at a distance R is \[B=\frac{{{\mu }_{0}}}{2\pi }\frac{i}{R}N{{A}^{-1}}{{m}^{-1}}\] Hence, magnetic field is same at both points P and Q.You need to login to perform this action.
