A small, flat coil of resitance `r` is placed at the centre of a large, closed coil of resistance `R`. The coils are coplanar. Their mutual inductance is `M`. Initially a constant current `i` was flowing in the inner coil. If this curent is suddenly swithced off, what charge will circulate in the outer coil?

A

`Mir//R^(2)`

B

`MiR//r^(2)`

C

`Mi//R`

D

`Mi//r`
