1. -1 points SerPSE9 31.P001 My Notes Ask Your A flat loop of wire consisting of a single turn of cross sectional area 8.20 cm2 is perpendicular to a magnetic field that increases uniformly in magnitude from 0.500 T to 1.60 T in 1.00 s. What is the resulting induced current if the loop has a resistance of 1.80 ?? mA Need Help?

My Note3 AgkYour The flexible loop in the figure below has a radius of 11.0 cm and is in a magnetic field of magnitude 0.100 T. The loop is grasped at points A and B and stretched until its area is nearly zero. If it takes 0.210 s to close the loop, what is the magnitude of the average induced emf in it during this time interval? mv Need HelpReadItExplanation / Answer
1. induced emf = rate of change of flux
= A dB/dt
= (8.20 x 10^-4 m^2) ( (1.60 - 0.5/1)
= 9.02 x 10^-4 Volt
I = e / R = 5.0 x 10^-4 A OR 0.50 mA
Ans: 0.50
