Question

Write an expression for magnetic field due to straight conductor
carrying current​

Answer 1

Answer:

Explanation:

Let point P lie in x-y plane and r→ is the position vector of point ' P ' with respect to Idl→ . Here dB→ is directed along negative Z-axis. The directions of dB→ at point P for all elements are same. This is the general expression for the magnetic field due to straight current.

Answer 2

Answer:

Magnetic field due to an infinitely long straight current carrying wire - definition. B=(2πr)μ0I where B is the magnitude of magnetic field, r is the distance from the wire where the magnetic field is calculated, and I is the applied current.
