A) P has more magnitude than Q.
B) Q has more magnitude than P.
C) P and Q have the same magnitude.
D) P and Q may have the same or more magnitude.
Correct Answer: C
Solution :
As shown in the above figure, at point P in the magnetic field (b) (situated east of the wire), the field of the current-carrying wire will be directed north while at point Q is (situated west of the wire), it will be directed south but since radius (d) is the same, both will have the same magnitude \[B={{\mu }_{0}}{i}/{2}\;\pi r\].You need to login to perform this action.
