Two identical long conducting wires 
and COD are placed at right angle to each other, with one above other such that 
is their common point for the two. The wires carry 
and 
currents, respectively Point 
is lying at distance 
from 
along a direction perpendicular to the plane containing the wires. The magnetic field at the point 
will be
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
The magnetic field at the point 
, at a perpendicular distance 
from 
in a direction perpendicular to the plane ABCD due to currents through 
and COD are perpendicular to each other. Hence,
