Composite wire section as it relates to induction

[tetra]

Stuff I'm wondering about:

* can/does a conductors' cross-section influence inductive efficiency and/or directionality?

* consider a 'wire' made from a dielectric material, with a conductive material evaporatively deposited on it's surface. if this wire were asymmetrical in section, e.g. it was mostly flat, with one side smooth, and the other side wavy, with far more surface area on that side, wound into a flat spiral coil like a disk (with smooth side being 'heads', and wavy side being 'tails'). Would the electromagnetic forces also be asymmetrical relative to the centerline of this wire, being more strong on the wavy side?

* am I way, way off base here?

Thanks

Yes it does.

@zoki85 Thanks for replying to #1. I intuited the same. Do you have any idea about the second question? My thought is yes about #2 (asymmetrical sides) as well, and I think it has to do with the skin effect of the conductor. I'm not sure about the composite behavior though - or if a 'hollow' wire makes a difference in the overall behavior.

Yes, the effective inductivity also depends on the frequency (and skin effect)

for your inquiry about composite wire sections and their relationship to induction. I can provide some insights on these questions that you have raised.

To answer your first question, yes, the cross-section of a conductor can indeed influence the efficiency and directionality of induction. This is because the shape and size of the conductor can affect the magnetic field that is generated around it when an electric current flows through it. A larger cross-section can result in a stronger magnetic field, while a more symmetrical shape can lead to a more uniform distribution of the field. This is important in induction, as a stronger and more uniform magnetic field can result in a more efficient transfer of energy.

Your second question raises an interesting scenario of a wire made from a dielectric material with a conductive material deposited on its surface. In this case, the electromagnetic forces would indeed be asymmetrical relative to the centerline of the wire. This is because the wavy side of the wire would have a larger surface area, resulting in a stronger magnetic field being generated on that side. This could potentially lead to a directional flow of energy in the coil, with more energy being induced on the wavy side compared to the smooth side.

However, it is important to note that the overall design and construction of the coil would also play a significant role in the directionality and efficiency of induction. The spacing and orientation of the turns in the coil, as well as the material properties of the wire, would also have an impact on the electromagnetic forces and resulting induction.

In conclusion, your ideas and questions about composite wire sections and their relationship to induction are certainly valid and worth exploring. As with any scientific inquiry, it is important to consider all factors and variables involved in a system to fully understand and predict its behavior. I hope this response has provided some insight and further avenues for exploration in your research.
