A long, straight wire carrying a current of 245 A is placed in a uniform magnetic field that has a magnitude of 6.40 10-3 T. The wire is perpendicular to the field. Find a point in space where the net magnetic field is zero. Locate this point by specifying its perpendicular distance from the wire.

Respuesta :

Answer:

0.076 m

Explanation:

Given,

Current in the wire,I = 245 A

Magnetic field, B = 6.40 x 10⁻³ T

perpendicular distance,r = ?

Using magnetic field formula

[tex]B=\dfrac{\mu_0 I}{2\pi r}[/tex]

[tex]r=\dfrac{\mu_0 NI}{2\pi B}[/tex]

[tex]r=\dfrac{4\pi\times 10^{-7}\times 245}{2\pi \times 6.40 \times 10^{-3}}[/tex]

r = 0.076 m

Hence, Perpendicular distance from the wire is equal to  0.076 m
