The heat comes from physical objects ; In all your examples . Billvon .

But the heat itself that is introduced is not a physical object. Nor does it have to come from a physical object. Indeed, it could come via magnetic fields (as in an induction cooker) or via photons (as in a broiler.)

Heat is not a physical thing you can extract from the pot. It is a PROPERTY of the pot and its contents.

What magnetic field exists without a physical object , as its source ? None .

Magnetic fields exist wherever current flows.

Heat is not a physical thing you can extract from the pot. It is a PROPERTY of the pot and its contents.
Magnetic fields are not a physical thing you can grab and take with you. It is a FIELD that exists in space.

At this point I have to note that you seem to know nothing about physics. Perhaps, instead of wasting your time making ignorant and incorrect statements here, you could spend your time more wisely in a classroom learning about this stuff?

Why does the current flow ?

Why does the current flow ?

While this has been fun, I will repeat my earlier comment. You would be best served by going to a classroom to learn basic physics. I don't have time to teach an entire course here.

The Magnetic field expands space .

Because of the source of the magnetic field .

 

[billvon]

The Magnetic field expands space. The higher the energy the larger the Magnetic field .

No and no. Again, basic physics course would help here.

The " explosion " expands space .

Disagree .

 

[billvon]

The " explosion " expands space .

Nope. No explosion. Just physics.

 

[river]

I see ; explain further .

 

[river]

Without the physical object there is no magnetic field .

Particle energy is not the same as electromagnetic energy , which is a wave .

River:

Energy comes in many forms, and one can be converted into another.

Electromagnetic energy, which is propagated by photons, can be converted into heat energy, such as the motion of atoms.
Gravitational potential energy can be converted into kinetic energy - say, by letting a ball drop - and then into other forms of energy, such as heat, when it hits the ground. This heat can be radiated in the form of electromagnetic energy, such as infrared photons, etc.

They're all energy. Energy is an accounting system for the potential to do "work".

Magnetism:

As you may have gathered, from the term electromagnetism, all forms of EM, including light, are comprised of an electric field oscillating with a magnetic field. This is carried by photons - massless particles.

And before you say 'did they come from physical things?' I'll point out to you that photons (electromagnetism) came first in the universe, matter followed later.

Then upon what is electromagnetism based . If not anything physical ?

Electromagnetism is one of the four fundamental forces of the universe (along with weak, strong and gravity).
The entire universe can be explained by the interaction of the dour fundamental forces.

The electromagnetic force is carried by massless photons.

Which leads to entropy .

To your last statement ; How ?

The electromagnetic is a wave .

Don't understand your point .

In this link , what are you trying to prove ?

Where do the photons originate ?

 

[DaveC426913]

Don't understand your point .

You're asking how electromagnetism and photons work.
At some point, if you're interested, you'll have to read up a little on things. It will take forever to get it if you do it one question and answer at a time.

No , not really .

I asked where do photons originate ?

What is the source of photons ?
