(a) How is self-inductance defined and what physical principleallows us to define it ?
(b) In discussing LRC circuits we found that comparison withsimple oscillating mechanical systems such as a mass on a springwith friction was very useful. Using this analogy, what are themechanical equivalents of: charge, current, inductance,capacitance, and magnetic flux ?
(c) Derive from basic principles the self-inductance of asolenoid having cross sectional area A, length L and Nwindings.
