4-A rigid circular loop of wire is not connected to an external voltage source but is located in a region of space where there is a strong and constant magnetic field... Because the loop and the magnetic field are fixed perpendicular to each other, cose=1 at all times... When the value of the magnetic flux PB = |B|Acose is calculated it is found to be a large value... Based on the information provided, which of the following choices below best represents the electric potential difference/emf induced in this circular loop of conducting wire?
