To determine which electromagnet will produce the strongest magnetic force, we need to consider two key factors: the current intensity and the number of turns in the wire.
The strength of the magnetic field (B) created by an electromagnet can be approximated using the formula:
\[ B = \mu_0 \times \frac{N \times I}{L} \]
Where:
- \( B \) is the magnetic field strength,
- \( \mu_0 \) is the permeability of free space (a constant),
- \( N \) is the number of turns of wire,
- \( I \) is the current intensity,
- \( L \) is the length of the solenoid (not provided but can be assumed to be the same for all in this comparison).
From your data:
1. Electromagnet W: Current = medium, Turns = 10
2. Electromagnet X: Current = low, Turns = 10
3. Electromagnet Y: Current = medium, Turns = 50
4. Electromagnet Z: Current = low, Turns = 50
- **Comparing the current intensities**:
- Medium would provide a stronger current compared to low.
- **Comparing the number of turns**:
- More turns generally produce a stronger magnetic field.
From these comparisons:
1. **W (medium current, 10 turns)**: Medium current but only 10 turns.
2. **X (low current, 10 turns)**: Low current, 10 turns. Weakest of all.
3. **Y (medium current, 50 turns)**: Medium current, 50 turns. More turns than W, which likely results in stronger magnetic force.
4. **Z (low current, 50 turns)**: Low current but with more turns than X or W. However, the low current reduces its effectiveness.
**Conclusion**: Electromagnet **Y** will produce the strongest magnetic force because it has a medium current intensity and the highest number of turns (50).
