The strength of an electromagnet is determined by both the current intensity and the number of turns. In this case, Electromagnet P has a medium current intensity and 20 turns, making it the strongest. Electromagnets Q and R both have low current intensities, but since Q has more turns (20 vs 15 for R), it is stronger.
Therefore, the correct order from strongest magnetic force to weakest magnetic force is: a. P, Q, R
Use the table to answer the question.
| Electromagnet | Current Intensity | Number of Turns |
| P | medium | 20 |
| Q | low | 20 |
| R | low | 15 |
Which list shows the electromagnets in order from strongest magnetic force to weakest magnetic force?
a. P, Q, R
b. Q, R, P
c. R, P, Q
d. R, Q, P
