I say it can...

I say they both can, according to what I've studied...

I call a magnetic field "physical". What else is it? Spiritual? :-)
I know you mean mechanical, not physical. The same electromagnetic force
that induces currents in inductors, holds atoms together, and keeps them

A mutualy inductive circuit is commonly simulated or modeled with a series
coupling inductance, the value of which is depends on K. So you can then
transform that to a direct mechanicaly analog circuit.

I think so.
