A rectangular loop with dimensions 4.20 cm by 9.50 cm carries current III. The current in the loop produces a magnetic field at
the center of the loop that has magnitude 5.40×10−5 T and direction away from you as you view the plane of the loop.
What are the magnitude and direction (clockwise or counterclockwise) of the current in the loop?

Answer:
correct option is a. 0.2 mA toward D
Explanation:
given data
B carries = 1.5 mA
C carries current = 1.3 mA
solution
we take positive direction of current going away from the point D
and negative direction of current coming towards point D
so we use here kirchoff's current law that is
iA + iB + iC = 0 ......................1
iA + 1.5 + (-1.3) = 0
iA = - 0.2 mA
so that current in wire A is 0.2 mA towards point D
correct option is a. 0.2 mA toward D
