asked • 07/16/23The magnetic flux that passes through one turn of a 15-turn coil of wire changes to 3.51 from 9.63 Wb in a time of 0.0559 s. The average induced current in the coil is 287 A. What is the resistance of the wire?
The answer is not 5.74 ohms.

Be careful here, the magnetic flux is ONLY through ONE loop of the wire!

Oh, I see. Yes, that is worded very strangely... Glad I could help!07/17/23

Thank you! The answer you gave at the end is correct for 1 turn, but the problem answer was actually asking for 15 turns even though it was worded tricky and made you think its just for 1. Your step by step cleared it up completely though! thank you again!07/16/23
