in time t the angle between the B and area= θ
Einduced= -d(φb)/dt=-Bd(Acoswt)/dt=BAwsinwt=E0sinwt
so thermal power= 0∫2π/wE0sinwt*idt
but i= E0sinwt/R
so total thermal power(after calculating )= (E02/2R )T
hence mean thermal power = E02/2R
sry forgot to mention E0=BÏ€a2w/2

hey area is A/2 since its a semi circle so that's it...
