i) a circular coil with radius 20 cm is placed with it's plane parallel and between two straight
wires p and q. the coil carries current i = 0.5a . i for coil is in clockwise direction when viewed
from left side. wire p is located 40 cm to the left of a circular coil and carries current i = 0.2a
while wire q is located 80 cm to the right of the circular coil and carries current l = 0.6a. both
i for p and l for q are in the same directions into the paper. determine the resultant of magnetic field at
the centre of a circular coil from the top view.
ii) if the current in wire p is out of the page, determine the resultant of magnetic field at the centre
of a circular coil.
