Use the table to answer the question.
Electromagnet P Q R
Current Intensity medium low low
Number of Turns 20 20 15
Which list shows the electromagnets in order from strongest magnetic force to weakest magnetic force?
A) R, P, Q
B) Q, R, P
C)R, Q, P
D)P, Q, R
C) R, Q, P (Since the current intensity is low for all three, the number of turns becomes the determining factor for strength. Hence, R with 15 turns would have the strongest magnetic force, followed by Q with 20 turns, and then P with 20 turns but lower magnetic force due to lower current intensity.)
To determine the order of electromagnets from strongest to weakest magnetic force, we need to consider both the current intensity and the number of turns.
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.
Considering that increasing the number of turns strengthens the magnetic force, and increasing the current intensity also strengthens the magnetic force, we can conclude that the order from strongest to weakest magnetic force is:
A) R, P, Q
