Hello.. i have been trying to solve this problem for my online hw:
A coil with 300 turns of wire, a total resistance
of 46 Ω, and a cross-sectional area of 0.25 m2
is positioned with its plane perpendicular to
the field of a powerful electromagnet.
What average current is induced in the coil
during the 0.23 s that the magnetic field drops
from 2.0 T to 0.0 T?
I got -14.17769376.. but it keeps marking it wrong ):
please help me i dont know what i am doing wrong D:
tHanks in advance

I agree with your answer ..
E = (-) 652.20V
i = (-)14.18 A
Have you tried entering 14.18 (as positive value) ?
Could it be rejecting an answer given to too many dec. places (as unjustified precision)?
