50 A current in north to south direction. Give the magnitude and direction of `vecB` at a point` 2.5` m east of the wire.

Explanation

To solve the problem of finding the magnitude and direction of the magnetic field (B) at a point 2.5 m east of a wire carrying a 50 A current from north to south, we can follow these steps:

### Step 1: Identify the formula for the magnetic field around a straight current-carrying wire
The magnetic field (B) at a distance (d) from a long straight wire carrying a current (I) is given by the formula:
\[ B = \frac{\mu_0 I}{2\pi d} \]
where:
