A square loop of wire with 10 turns and a side length of 3 cm
sits in a uniform magnetic field that is decreasing at a rate 0.25
T/s and is directed into the page. The resistance per unit length
of the wire is 0.002 Ω/m .
a) Find the induced EMF in the loop.
b) Find the magnitude and direction of the induced current in
the loop.
c) If a capacitor of capacitance 10 F is part of the wire loop
determine how much charge has built up on the capacitor after 0.03
s have elapsed.
