Find the magnetic field at the centroid of an equilateral triangle of side` 0.03` m and a current 2 A flowing through the sides of it.

Explanation

To find the magnetic field at the centroid of an equilateral triangle with a side length of 0.03 m and a current of 2 A flowing through its sides, we can follow these steps:

### Step 1: Understand the Geometry
The centroid of an equilateral triangle is located at a point where all three medians intersect. For an equilateral triangle, the distance from each vertex to the centroid is \( \frac{2}{3} \) of the median.

### Step 2: Calculate the Length of the Median
The median \( m \) of an equilateral triangle can be calculated using the formula:
\[
