Magnetic field due to currentHard
Question
Two mutually perpendicular conductors carrying currents I1 and I2 lie in one plane. Locus of the point at which the magnetic induction is zero, is a
Options
A.circle with centre as the point of intersection of the conductor
B.parabola with vertex as the point of intersection of the conductors
C.straight line passing through the point of intersection of the conductors
D.rectangular hyperbola
Solution
The velocity, vector normal to 
gives rise to magnetic force which rotates the charge particle in a circle. The velocity vector parallel to 
moves it in a straight line. The resultant is a helical path.
