Question
A rectangular loop of area A=0.160
m2 is placed in a region where the
magnetic field is perpendicular to the
plane of the loop. The magnitude of
the field is allowed to vary in time
according to B=0.411et/2, where B is
in teslas and t is in seconds. What is
the value for induced emf ( in units of
mV) at t= 4.5 s?
