Calculate the magnetic induction of the field created by a very long straight line at a point located at a distance of r = 10 cm from it. The conductor is located in a vacuum and an electric current passes through it with a current strength I = 10 (2 degrees) A.

Since here we are talking about an infinitely long conductor (we can see this by the difference in the angles alpha 1 and alpha 2 formed by a triangle)
Then B = ((μ0 * μ * I) / (2π * r)) * (For the angle difference alpha 1 – alpha 2) = (4π * 10 ^ -7 * 1 * 100) / (2π * 0.1) * 1 = 2000 * 10 ^ -7 T = 0.2 mT
