Figure below shows a square loop of side 0.5 m and resistance 10 Ω. The magnetic field has a magnitude B = 1.0 T. The work done in pulling the loop out of the field slowly and uniformly in 2 second is 


(1) 3.125 × 10–3 J          (2) 6.25 × 10–4 J               (3) 1.25 × 10–2 J             (4) 5.0 × 10–4 J
