# Two coils ‘P’ and ‘Q’ are separated by some distance.  When a current 3 A flows through the coil ‘P’, a magnetic flux of  Wb passes through Q.  No current is passed through ‘Q’.  When no current passes through ‘P’ and a current of 2 A passes through ‘Q’, the flux through ‘P’ is (a) 6.67 10−3 Wb (b) 6.67 10−4 Wb (c) 3.67 10−3 Wb (d) 3.67 10−4  Wb

Answer Key : (b) -

=Mi

⇒103=M(3)

=M(2)

∴  =

QP= =6.67 Wb.
