Physics

(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.

aThe property of selfinductance is a particular form of electromagnetic induction Self inductance is defined as the induction of a voltage in a currentcarrying wire when the current in the wire itself is changing In the case of selfinductance the magnetic field created by a changing current in the circuit itself induces a voltage in the same circuit    See Answer
