The unit of self inductance is

Radii of two conducting circular loops are b and a respectively where b > > a. Centers of both loops coincide but planes of both loops are perpendicular to each other. The value of mutual inductance for these loops

If the current in the toroidal solenoid increases uniformly from zero to $6.0\, A$ in $3.0?s.$ Self inductance of the toroidal solenoid is $40?H$. The magnitude of self induced emf is
