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