Find the magnetic field produced by a long straight conductor of length L carrying current I of negligible area of cross section at a point on the conductor itself?

Expert Answer:

Since the point lies on the conductor itself, therefore θ = 0 = sin θ = 0

According to Biot Savart’s Law

For sin θ = 0, dB = 0

Therefore, there is no magnetic field induction at any point on the thin linear current carrying conductor.
