154845 What is self inductance of a coil when a charge of current from 0 to $2 \mathrm{~A}$ in 0.05 second induces an emf of $40 \mathrm{~V}$ in it?

154846 Two concentric coils of 10 turns each are placed in the same plane. Their radii are $20 \mathrm{~cm}$ and $40 \mathrm{~cm}$ and carry $0.2 \mathrm{~A}$ and $0.3 \mathrm{~A}$. current respectively in opposite directions. The magnetic induction (in tesla) at the centre is

154847 A coil of $N=100$ turns carries a current $I=5 A$ and creates a magnetic flux $\phi=10^{-5} \mathrm{Tm}^{-2}$ per turn. The value of its inductance $L$ will be :
