To determine the strength of the magnetic force of each electromagnet, we consider both the current intensity and the number of turns in the wire. Generally, higher current intensity and more turns in the wire will produce a stronger magnetic field.

Let's evaluate each electromagnet:

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

Comparing the three:

  1. Electromagnet K has medium current and 20 turns, which typically gives it the weakest magnetic force.
  2. Electromagnet J has high current with 20 turns, which is stronger than K.
  3. Electromagnet L has high current with 45 turns, which should provide the strongest magnetic force due to both factors being high.

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

K, J, L

So, the answer is:

K, J, L
