To determine the strength of the magnetic force of the electromagnets, we can consider both the current intensity and the number of turns in the wire. The magnetic force is generally stronger with higher current intensity and a greater number of turns.

Let's analyze the provided sets of electromagnets:

  1. Electromagnet J

    • Current Intensity: high
    • Number of Turns: 20

  2. Electromagnet K

    • Current Intensity: medium
    • Number of Turns: 20

  3. Electromagnet L

    • Current Intensity: high
    • Number of Turns: 45

Now we can compare:

  • Electromagnet J: High current and 20 turns
  • Electromagnet K: Medium current and 20 turns
  • Electromagnet L: High current and 45 turns

Electromagnet L has the highest magnetic force, as it has high current and the most turns. Electromagnet J follows, since it has high current but fewer turns. Electromagnet K has the weakest magnetic force because it has medium current and the same number of turns as J.

Thus, the correct order from weakest magnetic force to strongest is:

K, J, L

The answer is: K, J, L.
