A semi-infinite straight wire lies along the x-axis, from the origin to x = +[infinity]. The magnetic field on the y-axis at y = 0.044 m is 3.4 μT . What is the current through the wire?

Respuesta :

Answer:

I = 1.496A

Explanation:

B = (U₀ I/4πr) =3. 4 × 10⁻⁶T

3. 4 × 10⁻⁶ = 10⁻⁷ × I/0.044

I = 1.496A
