To determine which electromagnet will produce the strongest magnetic force, we need to consider both the current intensity and the number of turns in the wire.

The strength of an electromagnet's magnetic field can be estimated using the formula:

\[ B \propto n \cdot I \]

where:

  • \( B \) is the magnetic field strength,
  • \( n \) is the number of turns of wire,
  • \( I \) is the current intensity.

Let's analyze each electromagnet based on the given data:

  • Electromagnet W: medium current (I), 10 turns
  • Electromagnet X: low current, 10 turns
  • Electromagnet Y: medium current (I), 50 turns
  • Electromagnet Z: low current, 50 turns

Now we can assign values to the current intensity:

  • Medium current can be considered higher than low current, so for the sake of comparison let's consider:
    • Medium = 1
    • Low = 0.5

Now we will calculate the effective strength for each electromagnet:

  1. Electromagnet W: \( B \propto 10 \cdot 1 = 10 \)
  2. Electromagnet X: \( B \propto 10 \cdot 0.5 = 5 \)
  3. Electromagnet Y: \( B \propto 50 \cdot 1 = 50 \)
  4. Electromagnet Z: \( B \propto 50 \cdot 0.5 = 25 \)

From these calculations, the strongest magnetic force is produced by:

  • Electromagnet Y with an effective strength of 50.

Therefore, the answer is:

electromagnet Y.
