Energy - Magnetic Energy

field electrical iron associated

A magnetic is a piece of metal that has the ability to attract iron, nickel, cobalt, or certain specific other kinds of metal. Every magnet contains two distinct regions, one known as the north pole and one, the south pole. As with electrical charges, unlike poles attract each other and like poles repel each other.

A study of magnets allows the introduction of a new concept in energy, the concept of a field. An energy field is a region in space in which a magnetic, electrical, or some other kind of force can be experienced. For example, imagine that a piece of iron is placed at a distance of 2 in (5 cm) from a bar magnet. If the magnet is strong enough, it may pull on the iron strongly enough to cause it to move. The piece of iron is said to be within the magnetic field of the bar magnet.

The concept of an energy field was, at one time, a very difficult one for scientists to understand and accept. How could one object exert a force on another object if the two were not in contact with each other? Eventually, it became clear that forces can operate at a distance from each other. Electrical charges and magnetic poles seem to exert their forces throughout a field along pathways known as lines of force.

One of the great discoveries in the history of physics was made by the English physicist James Clerk Maxwell (1831-1879) in the late nineteenth century. Maxwell found that the two major forms of energy known as electricity and magnetism are not really different from each other, but are instead closely associated with each other. That is, every electrical current has associated with it a magnetic field and every changing magnetic field creates its own electrical current.

As a result of Maxwell's work, it is often more correct to speak of electromagnetic energy, a form of energy that has both electrical and magnetic components. Scientists now know that a number of seemingly different types of energy are all actually forms of electromagnetic energy. These include x rays, gamma rays, ultraviolet light, visible light, infrared radiation, radio waves, and microwaves. These forms of electromagnetic energy differ from each other in terms of the wavelength and frequency of the energy wave on which they travel. The waves associated with x rays, for example, have very short wavelengths and very high frequencies, while the waves associated with microwaves have much longer wavelengths and much lower frequencies.

Is there a way to take the energy from the space between a magnet and a peace of metal and convert it to electric?

Magnetic energy is found in eanything as the electromagnetism which is what is measur in the electromagnetic spectrum. by the way magnets can be manufactured and alone or combinated are a source of energy

In my calculations i have researched that the magnetics force is the most strongest force in the world other than gravity!

majority says magnetic energy, if it is manufactured, comes from the total energies being used to produce such a thing. but my mind keep asking, suppose a manufactured magnet is used in a wind generator, do you think that generator will stop if the total energy use to produce that magnet has already been attained? will the magnet ceased being a magnet after the same amount of energy is produced from a generator?

I would like to know if a electrically charged metal, such as nickel, be attracted to the electromagnetic wave it produces? eg: a surfboard riding an ocean wave.

So there is such things as magnetic energy. Is it included as kinetic energy or potential energy? Is magnetic energy a movement or a stored energy?

Hmm... In case any of you were wondering, magnetic potential energy is defined by 1/2 the square of the closed loop inductance (Integrate B around the path) multiplied by the loop reluctance. This is analogous to the inductively stored energy in an inductor, W = 1/2 L I^2, or the energy stored in a capacitor, 1/2 C V^2. Even to kinematic energy, 1/2 m V^2. All the same form.

None of this has anything at all to do with movement, nuclear energy, manufacturing hard (permanent) magnets, extracting energy from a rotating field (a wind generator), the electromagnetic spectrum, etc. Magnetic energy is just the potential for work in a magnetic field.

I am working on projects such as the articles I have been reading through your forums. Where can I get more project based information and controls for the projects? I am currently trying to find scholarships and grants to find new ways for America to prosper and succeed in energy related roles and cannot stand the corruption based societies we live. If anything comes to mind can you send me a lead.
