Question 1
a)
1) 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 icoil = 0.5a . icoil 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 ip = 0.2a
while wire q is located 80 cm to the right of the circular coil and carries current lo =0.6a. both
ip and iq 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.
