Answer 1

To determine the order of the electromagnets from strongest to weakest magnetic force, we consider both the current intensity and the number of turns in the wire.

- Electromagnet J: Current intensity = high, Number of turns = 20
- Electromagnet K: Current intensity = medium, Number of turns = 20
- Electromagnet L: Current intensity = high, Number of turns = 45

The strength of an electromagnet generally increases with higher current intensity and a greater number of turns. Therefore, Electromagnet L, with high current intensity and the highest number of turns (45), is the strongest.

Next, Electromagnet J also has high current intensity but only 20 turns, making it stronger than K. Electromagnet K, with medium current intensity and 20 turns, is the weakest of the three.

So, the order from strongest to weakest magnetic force is:

1. L (strongest)
2. J
3. K (weakest)

Given the options available, the correct order from strongest to weakest is:

**OLJK**
