Answer 1

To determine the strength of the electromagnets, we look at both the current intensity and the number of turns. According to the data provided:

- **Electromagnet P**: medium current (20 turns)
- **Electromagnet Q**: low current (20 turns)
- **Electromagnet R**: low current (15 turns)

Given that a higher current intensity and a higher number of turns both contribute to stronger magnetic forces, we can make the following assessments:

1. **Electromagnet P** has a medium current level but the highest number of turns (20) among those with medium or low current.
2. **Electromagnet Q** has a low current with 20 turns.
3. **Electromagnet R** has a low current with the lowest number of turns (15).

Thus, in order from strongest to weakest magnetic force:

1. **P** (medium current, 20 turns)
2. **Q** (low current, 20 turns)
3. **R** (low current, 15 turns)

The correct order is: **P, Q, R**.

So the choice is:

**P, Q, R**
