Question

Magnetic field due to a straight conductor depends on.

(a) Current
(b) Distance
(c) Both (a) and (b)
(d) cross sectional area of wire

Need a correct answer from brainly toppers :)​

Answer 1

Answer:

The direction of magnetic field is vector cross product dlX r, which is clearly perpendicular to the plane xy. This means that the magnetic field is along z-axis.

Explanation:

Magnetic field due to current in straight wire Magnetic fields due to all current elements constituting straight wire at a point P are same.

Answer 2

Answer:

(a). Current

Explanation:

this is your answer

but I have a paragraph I will give you but don't write that okay

The magnetic field at a point due to a current-carrying conductor depends on the current through the conductor and the distance of the point from the conductor . (1) The magnitude of the magnetic field produced at a given point is directly proportional to the magnitude of the current passing through the conductor .

means your answer is current okey

पर आप इस paragraph को मत लिखिएगा। ok
