Suppose a cube of volume `2mm^(3)` is placed at the centre of a circular loop of radius 5 cm carrying current 2A.
Find the magnetic energy stored inside the cube.

Explanation

To find the magnetic energy stored inside the cube placed at the center of a circular loop carrying current, we can follow these steps:

### Step 1: Convert the volume of the cube to SI units
The volume of the cube is given as \(2 \, \text{mm}^3\). To convert this to cubic meters:
\[ V_{\text{cube}} = 2 \, \text{mm}^3 = 2 \times 10^{-9} \, \text{m}^3 \]
