Does Voltage Create a Physical Field Similar to Magnetic Fields from Current?

AI Thread Summary
Voltage does not create a physical field in the same way that current produces a magnetic field; rather, it is a measure of electrical potential. An electric field exists when there is a potential difference, but this does not imply that voltage itself produces the field. Charge is responsible for generating an electric field, similar to how current generates a magnetic field. The discussion highlights the distinction between voltage as a potential and the actual presence of electric fields. Ultimately, understanding the relationship between voltage, charge, and electric fields is crucial in electrical theory.

Does voltage produce a physical field, like how a current produces a magnetic field?
 
Physics news on Phys.org
Is there a field around a battery?
 
Current is a measure of flow of electrons and that produces a magnetic field.
Voltage is a measure of electrical potential, no electrons need to flow anywhere for a voltage, so no field
 
Voltage is a measure of potential or potential difference in an electric field.
If there is potential difference there is an electric field.
But I won't say that the field is "produced" by the potential difference. Both potential and intensity of the field are just quantities used to describe the field. None of them "produce" the field.
Same as matter is not produced by density or motion is not "produced" by speed.

don't be so sure of that :wink:

an energised capacitor has a potential difference between/across the plates
it also has an electric field between the plates

I'm under the impression that a voltage is a result of an electric or magnetic field, not that it creates a field.

Charge produces an electric field (and the associated potential, i.e. voltage), like how a current produces a magnetic field (and the associated magnetic vector potential).

(If you didn't intend "physical field" to mean "electric field", then you should explain what it means to you.)
