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.)
