Answer 2

The magnetic field produced at a point 1 meter away from infinitely long straight wire is $2\times 10^{-7}\ T$.

Explanation:

It is given that,

Current, I = 1 A

Let B is the magnetic field produced at a point 1 meter away from infinitely long straight wire. It is given by the following relation as :

$B=\dfrac{\mu_oI}{2\pi d}$

d = 1 m

$B=\dfrac{4\pi \times 10^{-7}\times 1}{2\pi \times 1}$

$B=2\times 10^{-7}\ T$

So, the magnetic field produced at a point 1 meter away from infinitely long straight wire is $2\times 10^{-7}\ T$. Hence, this is the required solution.
