Electromagnetic Induction · Induction laws

A conducting circular loop of area 1.0 m21.0\ \mathrm{m^2} is placed perpendicular to a magnetic field which varies as B=sin⁡(100 t)B = \sin(100\,t) Tesla. If the resistance of the loop is 100 Ω100\ \Omega, then the average thermal energy dissipated in the loop in one period is J.
