NEETPhysicsMoving Charges and MagnetismMCQ+4 / −1
Two identical long conducting wires AOBAOBAOB and CODCODCOD are placed at right angle to each other, with one above other such that OOO is their common point for the two. The wires carry III1 and III2 currents, respectively. Point PPP is lying at distance f from OOO along a direction perpendicular to the plane containing the wires. The magnetic field at the point PPP will be

Correct answer: D

AIPMT 2014 Physics - Moving Charges and Magnetism Question 66 English Explanation

B1=μ0I12πd(−j^){B_1} = {{{\mu _0}{I_1}} \over {2\pi d}}\left( { - \widehat j} \right)B1​=2πdμ0​I1​​(−j​)

B2=μ0I22πd(−i^){B_2} = {{{\mu _0}{I_2}} \over {2\pi d}}\left( { - \widehat i} \right)B2​=2πdμ0​I2​​(−i)

B=B12+B22B = \sqrt {B_1^2 + B_2^2} B=B12​+B22​​

=μ02πd×I12+I22= {{{\mu _0}} \over {2\pi d}} \times \sqrt {I_1^2 + I_2^2}=2πdμ0​​×I12​+I22​​
