Two coil $A$ and $B$ have coefficient of mutual inductance $M = 2H$. The magnetic flux passing through coil $A$ changes by $4$ Weber in $10$ seconds due to the change in current in $B$. Then
- A
change in current in $B$ in this time interval is $0.5A$
- B
the change in current in $B$ in this time interval is $2A$
- C
the change in current in $B$ in this time interval is $8A$
- D
a change in current of $1A$ in coil $A$ will produce a change in flux passing through $B$ by $4$ Weber.
