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
1 answer
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.)
