A physicist works in a laboratory where the magnetic field is 2T She wears a necklace enclosing an area of 0 01m in such a way that the plane of the necklace is normal to the field and is having a resistance R 0 0102 Because power failure the field decays to 1T in time 10 3 The total heat produced in her necklace is 1 10 J 3 30 J 2 20 J 4 40 J
