A current of 10A is established in a long wire along the positive z-axis. Find the magnetic field `(vec B) at the point (1m , 0 , 0).

Explanation

To find the magnetic field \( \vec{B} \) at the point (1 m, 0, 0) due to a long straight wire carrying a current of 10 A along the positive z-axis, we can follow these steps:

### Step 1: Identify the parameters
We have:
- Current \( I = 10 \, \text{A} \)
- The wire is along the positive z-axis.
- The point of interest is at coordinates \( (1 \, \text{m}, 0, 0) \).
