B Is the Term Energy Field Misused in Physics?

[seazal]

A field like magnetic field has energy content, so it has energy field.

Is it wrong to use the word "energy field" in physics and why?

"Energy field" is a woo woo term, not a physics term

Can you point out the term "energy field" used in legitimate physics sources, so that it has a clear contextual definition?

Zz.

 

[seazal]

Remember Faraday introduced the concept of field to physics. According to Faraday, two electrically charged bodies can influence each other from a distance, even when they are not in contact with each other. This could be understood as the bodies being in an energy field through which they interact.

The above context of "energy field" is used correctly and meaningfully, is it not? It is everyday English and noun (or verb?) so it doesn't have to have legitimate contextual definition. Likewise when we described the LHC as huge. The word huge is everyday English and doesn't have to have a legitimate contextual definition.

A magnetic field expresses force, but however does not do _Work_ (viz. _Energy_).

Imbuing static magnetic fields with energy is one of the fallacies often indulged in by Free Energy enthusiasts.

Not really. There is an electromagnetic field which has an associated energy density, but the energy is seen as a property of the electromagnetic field rather than a separate field on its own. The electromagnetic field has several other properties in addition to the energy density.

I am not aware of any professional scientists using this terminology. Is there any particular motivation for saying “the energy field” instead of “the field’s energy” (density)?

It is not a fallacy at all. Poynting’s theorem shows pretty clearly that a static magnetic field has energy, and also shows how to remove that energy. This energy is readily apparent when a superconducting magnet quenches and rapidly dissipates it.

What kind of energy in physics where it has a separate field of its own? Can you give an example?

It is a medieval term which we must upgrade to modern form.

I don’t think there is one.

It is a medieval term which we must upgrade to modern form.

Or discard it. We have discarded many other medieval concepts. This seems like one that is already gone.

I noticed field has many meanings. I looked up the dictionary.

so the term "energy field".. can mean "energy region". Hence it is not incorrect to use the term "energy field" to describe "energy region"?

Do you think that you, single-handedly, are going to change physics nomenclature? Weird.

What do you want us to tell you? Can you use the term "energy field"? Absolutely. Is it wrong to use it? No, as there is no body within the mainstream scientific community that will come tape your mouth shut and slap you on the wrist for using it. Will you get odd looks from scientists and others for using it? Yes, as no one uses it that way and using it will almost certainly lead to many misunderstandings and be frustrating for others.

I understand it is not used in physics. But for non-physics usage, it is still correct grammar? we used the words grass field, economic field, etc. Can someone share what other "____ field" that people have genuinely used that is correct grammar? There is no linguistic forum here so let's share it here.

Ok, this topic is officially beaten to death now. This is not the Dictionary Forum nor the Grammar Forum. This is Physics Forums.

You have been clearly answered and correctly taught from a physics perspective. If you want grammar lessons you will need to find a different venue.
