Answer 1

To determine the strength of the electromagnets, we should consider both the current intensity and the number of turns in the wire. Generally, a higher current intensity and a greater number of turns will result in a stronger magnetic force.

Let's analyze the electromagnets:

- **Electromagnet J**: high current intensity, 20 turns
- **Electromagnet K**: medium current intensity, 20 turns
- **Electromagnet L**: high current intensity, 45 turns

1. **Electromagnet K** has medium current intensity and does not contribute as strongly as the others.
2. Between **J** and **L**, electromagnet L has a higher number of turns, which suggests it would produce a stronger magnetic force even if both have high current intensity.

Thus, we can deduce the order of electromagnetic strength based on the above observations:

- **Weakest**: K (medium current intensity)
- **Middle**: J (high current intensity with fewer turns)
- **Strongest**: L (high current intensity with more turns)

The correct order from weakest to strongest is:

**K, J, L**
