JEE MainPhysicsMagneticsMCQ+4 / −1

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
${{{\mu _0}} \over {2\pi d}}\left( {I_1^2 + I_2^2} \right)$
B
${{{\mu _0}} \over {2\pi }}{\left( {{{{I_1} + {I_2}} \over d}} \right)^{{1 \over 2}}}$
C
${{{\mu _0}} \over {2\pi d}}{\left( {I_1^2 + I_2^2} \right)^{{1 \over 2}}}$
D
${{{\mu _0}} \over {2\pi d}}\left( {{I_1} + {I_2}} \right)$
