Practice GUJCET Self-Inductance in the app →The SI unit of self-inductance $L$ is:The induced EMF in a coil due to changing current in itself is given by:The self-inductance of a long solenoid with $n$ turns per unit length, cross-section $A$ and length $\ell$ is:A solenoid of $N = 200$ turns, length $L = 20$ cm and cross-section $A = 5\ \text{cm}^2$ has self-inductance aA current of 4 mA in a coil of self-inductance 10 mH and 200 turns produces total flux:If the current in a coil of inductance 5 H changes from 2 A to 5 A in 0.1 s, the magnitude of induced EMF is:A toroid has major radius $R$ and small circular cross-section of radius $r$ ($r \ll R$), with $N$ turns. Its The self-inductance of a coaxial cable with inner-cylinder radius $a$ and outer-cylinder radius $b$, length $\
