Is Physic in need of a overhaul?

Question

When a magnet will attract iron for , well who knows. Why do physics still teach that energy can't be created when It seems obvious it is.

Answer 1

No, Physics is fine like it is (or at least the part you seem to question).

Magnets do not create energy.
In the case of a piece of Iron being attracted to a magnet, what might seem to be energy created out of no-where is actually coming from the fact that the Iron has a certain amount of initial potential energy by very virtue of it being located some distance away from the magnet.

First LAW of thermodynamics,
Energy can neither be created nor destroyed, it merely changes forms.

Answer 2

A magnet does not "create" energy any more than a stream "creates" energy when a water wheel was used to turn the gears of industry in years past. When you lift a stone high over your head, you have not "created" the potential energy added to the stone. The apparent energy that's created when a magnet pulls on the iron is exactly equal to the energy that's going to be required to separate the iron from the magnet - nothing is "created."

Answer 3

Your difficulty seems to be that sometimes the energy occurs in a form which, to you, is insensible. But it's there--there is energy in something called the electromagnetic field, for example, which is so real that it enables the computer you typed your message on to work. The description of these fields, and how the energy is stored, is rather mathematically involved in particular cases, and there is some degree of sophistication necessary to understand what the equations mean. But that doesn't mean the phenomena they describe is not real.

Answer 4

It cannot be created, however it can be changed in form and even from energy to matter and vice versa. I suggest you seek to understand however the difference between force and energy.
10,000,000 Volts of electromotive force applied across an open circuit is equal to 0kw of energy.

Answer 5

Once the magnet and iron are closest there is no further work which is defined as force distance occurs. If you separate them you perform work.
But yes physics needs an enema. It has been hijacked by mathematicians and the true physicists (natural philosophers) have been lost in the noise. We see proofs without observable phenomena but mathematically proved. Math is a construct of man not the same as observable phenomena.

Answer 6

We physics types teach that energy cannot be created because it cannot. It can only be transformed from one type to another. If you can creat energy out of nothing, let me know; we'll go into business and make billions, put opec out of business, etc.

Answer 7

wow.
This question is so out of my league.
You're question hurt my head as much
as did some of the answers.
