Transcribed Image Text:The figure shows a conducting
loop consisting of a half-circle of
radius r and three straight sections.
The half-circle lies in a uniform
magnetic field B that is directed
out of the page and is increasing
with time. The radius and the
magnetic field are given by the
following:
r = 0.20 m
r/2
B(t) = 3.0t² + 4.0t + 2.0
area of circle = ar²
What direction is the induced current in the loop?
Suppose the resistance of the loop is R = 2.0 Q. What is the magnitude of the induced
current at time t = 15 s?
