Mechanical Equivalent of an Inductor is a Mass
The mechanical analog of an inductor is a mass. The voltage
across an inductor
corresponds to the force
used to
accelerate a mass
. The current
through in the inductor
corresponds to the velocity
of the mass. Thus,
Eq.
(E.4) corresponds to Newton's second law for an ideal mass:



From the defining equation for an inductor [Eq.
(E.3)], we
see that the stored magnetic flux in an inductor is analogous to mass
times velocity, or momentum. In other words, magnetic flux may
be regarded as electric-charge momentum.
