To determine which electromagnet will produce the strongest magnetic force, we need to consider the formula for the magnetic force produced by an electromagnet, which is generally given by the equation:

\[ F \propto I \times N \]

Where:
- \( F \) is the magnetic force,
- \( I \) is the current intensity (higher current produces a stronger magnetic field),
- \( N \) is the number of turns in the wire (more turns result in a stronger magnetic field).

Now, let's analyze each electromagnet based on the provided information:

1. **Electromagnet W**:
- Current Intensity: 10 (medium)
- Number of Turns: 10
\[
F_W \propto 10 \times 10 = 100
\]

2. **Electromagnet X**:
- Current Intensity: X (low)
- Number of Turns: 10
\[
F_X \propto \text{low} \times 10 = \text{low}
\]

3. **Electromagnet Y**:
- Current Intensity: Y (medium)
- Number of Turns: Z (medium)
\[
F_Y \propto \text{medium} \times \text{medium} = \text{medium}
\]

4. **Electromagnet Z**:
- Current Intensity: 50 (low)
- Number of Turns: 50
\[
F_Z \propto 50 \times 50 = 2500
\]

Now let’s compare the values:

- Electromagnet W: 100
- Electromagnet X: low
- Electromagnet Y: medium
- Electromagnet Z: 2500

From this comparison, Electromagnet Z will produce the strongest magnetic force.

Thus, the answer is **electromagnet Z**.
