To determine the strength of the electromagnets based on the given information, we consider two main factors: the current intensity and the number of turns of wire.

The provided data is:
- Electromagnet P: Current intensity = 20, Number of turns = unspecified (assuming higher)
- Electromagnet Q: Current intensity = low, Number of turns = 20
- Electromagnet R: Current intensity = low, Number of turns = 15

Since we lack the exact values for the current intensity of P, we can make some assumptions based on the general trends:
1. Higher current leads to a stronger magnetic field.
2. More turns also contribute to a stronger magnetic field.

Given that P has a current intensity of 20, it is likely to have a stronger magnetic field compared to both Q and R, which have a low current.

Now considering the number of turns:
- Q has 20 turns, while R has 15 turns. This suggests that Q may have a stronger influence from the number of turns, despite having a lower current intensity than P.

Based on these considerations:
- P (with high current) should be the strongest.
- Q (with 20 turns but low current) should be next.
- R (with 15 turns and low current) should be the weakest.

Thus, the order from strongest to weakest magnetic force is: **P, Q, R**.

So the correct response is **P, Q, R**.
