Consider a circular wire loop that is getting warmer and is expanding slightly, so that its diameter can be written as D = Do + vt. There is a magnetic field perpendicular to the plane of the loop that is increasing, so that this uniform B field has strength B = Bo(1+ kt), where tis time. (a) Find the EMF induced in the wire loop and the current induced in the loop assuming that its resistance is equal to R. (b) Find the electric field inside the wire of the loop at the time t.
