  is :

To solve for the maximum value of the magnitude of \(\mathbf{B} - \mathbf{A}\), where \(\mathbf{B}\) and \(\mathbf{A}\) are vectors, we will consider the following approach:

### Step-by-step process:
1. **Define the vectors:**
   Let \(\mathbf{A}\) and \(\mathbf{B}\) be two vectors. The vector \(\mathbf{B} - \mathbf{A}\) represents the vector that points from \(\mathbf{A}\) to \(\mathbf{B}\).

2. **Magnitude of a vector:**
   The magnitude (or length) of a vector \(\mathbf{V} = \mathbf{B} - \mathbf{A}\) is given by:
   \[
   |\mathbf{B} - \mathbf{A}| = \sqrt{(B_x - A_x)^2 + (B_y - A_y)^2 + (B_z - A_z)^2}
   \]
   where \(B_x, B_y, B_z\) and \(A_x, A_y, A_z\) are the components of \(\mathbf{B}\) and \(\mathbf{A}\), respectively.

3. **Maximizing the magnitude:**
   The magnitude is maximized when the vectors \(\mathbf{B}\) and \(\mathbf{A}\) are pointing in opposite directions. In that case, the angle \(\theta\) between them is 180°, and the distance between the points represented by the vectors is greatest.

Thus, the maximum value of \(|\mathbf{B} - \mathbf{A}|\) is equal to the sum of the magnitudes of \(\mathbf{A}\) and \(\mathbf{B}\):
\[
|\mathbf{B} - \mathbf{A}|_{\text{max}} = |\mathbf{B}| + |\mathbf{A}|
\]

### Final Answer:
The maximum value of \(|\mathbf{B} - \mathbf{A}|\) is \(|\mathbf{A}| + |\mathbf{B}|\).
