To determine the order of the electromagnets from strongest magnetic force to weakest magnetic force, we need to consider both the current intensity and the number of turns in each electromagnet.
Looking at the table, we can see that electromagnet P has a medium current intensity and 20 turns, electromagnet Q has a low current intensity and 20 turns, and electromagnet R has a low current intensity and 15 turns.
Using this information, let's compare the electromagnets:
- Electromagnet P has a medium current intensity and 20 turns.
- Electromagnet Q has a low current intensity and 20 turns.
- Electromagnet R has a low current intensity and 15 turns.
Since the number of turns is the same for electromagnets P and Q, the one with the higher current intensity (P) will have a stronger magnetic force. Therefore, P should come first in the list.
Now, comparing electromagnets Q and R:
- Electromagnet Q has a low current intensity and 20 turns.
- Electromagnet R has a low current intensity and 15 turns.
Since the current intensity is the same for both electromagnets, the one with more turns (Q) will have a stronger magnetic force. Therefore, Q should come second in the list.
Finally, electromagnet R has the lowest magnetic force since it has both low current intensity and fewer turns. Therefore, R should come last in the list.
Combining these comparisons, the correct order from strongest magnetic force to weakest magnetic force is: P, Q, R.
So, the correct answer is: P, Q, R.
To determine the order of electromagnets from strongest to weakest magnetic force, we need to analyze the data in the table. The strength of an electromagnet depends on both the current intensity and the number of turns.
Looking at the table:
- Electromagnet P has a medium current intensity and 20 turns.
- Electromagnet Q has a low current intensity and 20 turns.
- Electromagnet R has a low current intensity and 15 turns.
To compare the magnetic forces, we need to consider both the current intensity and the number of turns. Since electromagnets P and Q have the same number of turns, we can focus on their current intensities. A medium current intensity is stronger than a low current intensity. Therefore, electromagnet P is stronger than electromagnet Q.
Comparing electromagnet R to the other two, we can again look at the current intensities. Both P and Q have a higher current intensity than R, meaning that R is the weakest among the three.
By analyzing the data, we can conclude that the correct order of electromagnets from strongest to weakest magnetic force is:
P, Q, R
