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