Two mutually perpendicular conductors carrying currents I1and I2lie in...
Magnetic field in X-Y plane at position (x,y) due to both wires must be zero
current carrying wire with current i1 is taken along X axis
now the magnetic field at the given point is
B1= μ0i1/2πy
now at the same point the magnetic field due to other wire placed along Y axis is given by,
B2= μ0i2/2πx
now we have to make the magnitude of magnetic field due to both wires same
so, B1=B2
μ0i1/2πy= μ0i2/2πx
now by solving above we have,
y=(i1/i2)x
so it’s a straight line with slope i1/i2 and passing from origin

To determine the locus of the point at which the magnetic induction is zero, we need to consider the magnetic fields produced by the two currents and find the point where the fields cancel out.

1. Magnetic Field due to I1:
The magnetic field produced at a point P due to a current carrying conductor can be given by the Biot-Savart law. For a straight conductor, the magnetic field at a point P located at a distance r from the conductor is given by:

B1 = (μ0 * I1) / (2πr)

where μ0 is the permeability of free space, I1 is the current in the conductor, and r is the distance from the conductor.

2. Magnetic Field due to I2:
Similarly, the magnetic field produced at point P due to the second conductor carrying current I2 can be given by:

B2 = (μ0 * I2) / (2πr)

3. Magnetic Field at Point P:
The total magnetic field at point P due to both conductors is the vector sum of the fields produced by I1 and I2. Since the conductors are mutually perpendicular, the magnetic fields are also perpendicular.

The resultant magnetic field at point P can be found using the Pythagorean theorem:

B = √(B1^2 + B2^2)

4. Magnetic Induction is Zero:
To find the locus of the point where the magnetic induction is zero, we need to find the point where the total magnetic field B is zero. This occurs when B1 and B2 are equal in magnitude but opposite in direction.

This condition can be expressed as:

B1 = -B2

Substituting the expressions for B1 and B2, we get:

(μ0 * I1) / (2πr) = -(μ0 * I2) / (2πr)

Simplifying, we find:

I1 = -I2

This equation represents a straight line passing through the point of intersection of the conductors. Hence, the correct answer is option 'C' - a straight line passing through the point of intersection of the conductors.
