Two identical conducting wires AOB and COD are placed at right angles to each other. The wire AOB carries an electric current I 1 and COD carries a current I 2 . The magnetic field on a point lying at a distance d from O, in a direction perpendicular to the plane of the wires AOB and COD, will be given by:
A
B
C
(I 1 + I 2 )
D
Text Solution
Verified by ExpertsThe correct answer is:
B
The magnetic field induction at a point 
at a distance 
from 
in a direction perpendicular to the plane of the wires and due to the currents through 
and 
as shown, are perpendicular to each other and it is
Hence,
