Physical Quantity Analogous to Inductance

AI Thread Summary
Inductance in electromagnetism can be analogized to a paddle wheel in hydraulics, where the wheel's mass and blade size limit the water flow's rate of change due to inertia. This analogy highlights the reluctance to change in both systems, with inductance resisting changes in current similar to how the paddle wheel resists changes in water flow. While the original question sought a heat transfer analogy, the discussion primarily focused on the hydraulic analogy instead. The concept emphasizes the relationship between inertia in mechanics and inductance in electrical systems. Understanding these analogies can enhance comprehension of physical principles across different domains.

Hi,

I understand that some physical quantities in electromagnetism are analogous to physical quantities in heat transfer. For instance, electric field is analogous to temperature gradient.

I want to know which physical quantity in heat transfer is analogous to Inductance ("L") ?

Regards,

hi tapan_ydv! welcome to pf! :smile:

i don't know about a heat transfer analogy,

but a hydraulics analogy is a paddle-wheel …

A heavy paddle wheel placed in the current. The mass of the wheel and the size of the blades restrict the water's ability to rapidly change its rate of flow (current) through the wheel due to the effects of inertia, but, given time, a constant flowing stream will pass mostly unimpeded through the wheel, as it turns at the same speed as the water flow …​

In mechanics...inertia

how? :confused:
 
Reluctance to change...as in a paddle wheel.

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...

Thread 'Why measure the speed of light in one direction?'

It may be shown from the equations of electromagnetism, by James Clerk Maxwell in the 1860’s, that the speed of light in the vacuum of free space is related to electric permittivity (ϵ) and magnetic permeability (μ) by the equation: c=1/√( μ ϵ ) . This value is a constant for the vacuum of free space and is independent of the motion of the observer. It was this fact, in part, that led Albert Einstein to Special Relativity.
