Correct answer
A towards
Step-by-step explanation
Two identical circular loops P and Q, each of radius , are separated by distance along their common axis. Current in P is and in Q is (both clockwise as seen from O).
Point O is at the midpoint. The magnetic fields from each loop at O:
(from P, pointing toward Q)
(from Q, pointing toward P)
Direction: towards Q.
Point O is at the midpoint. The magnetic fields from each loop at O:
(from P, pointing toward Q)
(from Q, pointing toward P)
Direction: towards Q.
