### Problem Description

In the diagram, current \( I_1 = 3.16 \, \text{A} \) is directed into the page, and current \( I_2 = 1.00 \, \text{A} \) is directed out of the page. The task is to calculate the magnitude of the magnetic field at point P. The distances given are \( s = 13.8 \, \text{mm} \) and \( d = 37.3 \, \text{mm} \). Express your answer in microteslas (µT).

### Diagram Explanation

- **Current \( I_1 \):** Illustrated with a symbol (circle with a cross), representing a current flowing into the page.
- **Current \( I_2 \):** Illustrated with a symbol (circle with a dot), representing a current coming out of the page.
- **Point P:** A point located between \( I_1 \) and \( I_2 \).
- **Distances:**
  - \( s \): Distance from \( I_1 \) to point P.
  - \( d \): Distance from \( I_2 \) to point P.
  
Use these details to calculate the magnetic field magnitude at point P using the formula for magnetic fields around a current-carrying wire.

A flux of \(2.0 \times 10^{-5} \, \text{T} \cdot \text{m}^2\) is maintained through a coil of area \(7.5 \, \text{cm}^2\) for \(0.50 \, \text{s}\). What emf is induced in this coil during this time by this flux?
