Electromagnetic Induction And Alternating Current Ques 18

18. A circular loop of radius $0.3 cm$ lies parallel to a much bigger circular loop of radius $20 cm$. The centre of the smaller loop is on the axis of the bigger loop. The distance between their centres is $15 cm$. If a current of $2.0 A$ flows through the bigger loop, then the flux linked with smaller loop is
