### Problem Statement

Determine the equivalent inductance \( L_{AB} \) (in \( mH \)) between terminals \( A \) and \( B \).

### Diagram Explanation

The diagram provided is an electrical circuit consisting of six inductors arranged in a combination of series and parallel connections. The inductors have the following inductance values:

- **200 mH**: Positioned at the top of the diagram.
- **300 mH**: Positioned at the right side, vertically aligned.
- **350 mH**: Positioned at the left side, vertically aligned.
- **400 mH**: Positioned at the bottom of the diagram.
- **600 mH**: Positioned horizontally between terminals \( A \) and \( B \).
- **700 mH**: Positioned directly below the 200 mH inductor, horizontally aligned.

### Connective Paths

- **Terminal A** is connected to a junction where the 600 mH, 700 mH, and 200 mH inductors meet. 
- **Terminal B** is connected directly to the other side of the 600 mH inductor and also links to the bottom 400 mH inductor.
- The 200 mH inductor is connected in parallel with a series combination of the 700 mH and 350 mH inductors.
- The circuit forms a loop in which the 300 mH inductor is in series with the above-mentioned parallel combination and the 400 mH inductor.

This setup requires calculating the overall inductance between terminals \( A \) and \( B \) by properly analyzing the combinations of parallel and series inductors.
