what is physics, you mean? Physics is literally the study of the physical properties of the world, such as speed, light, sound, weight, materials, heat and electrical conductivity, and basically everything else. Physics is the basis of almost every other field of science.

A magnet is an object that has a magnetic field. The word magnet comes from the Greek (magnētēs lithos), which means "magnesian stone". Magnesia was an area in Ancient Greece, in present-day Manisa, Turkey where deposits of magnetite have been discovered since antiquity.\n\nElectronic generation of magnetism\nElectrons play the primary role in generating a magnetic field. Within an atom, electrons can exist either individually or in pairs within any given orbital. When they are paired, the individuals in that pair always have opposite spin — one up, one down. The fact that the spins have opposite orientation means that the two cancel one another. If all electrons are paired, no net magnetic field will be generated.\n\nIn some atoms, there are electrons that are unpaired. All magnets have unpaired electrons, but not all atoms with unpaired electrons are ferromagnetic. In order for the material to become ferromagnetic, not only must there be unpaired electrons present, but those unpaired electrons must interact with one another over long ranges such that they are all oriented in the same way. The specific electron configuration of the atoms (as well as the distance between atoms) is what leads to this long range ordering. The electrons find that they can exist in a lower energy state if they all have the same orientation.\n\n\nNorth-south pole designation and the Earth's magnetic field\nA standard naming system for the poles of magnets is important. Historically, the terms north and south reflect awareness of the relationship between magnets and the earth's magnetic field. A freely suspended magnet will eventually orient itself north-to-south, because of its attraction to the north and south magnetic poles of the earth. The end of a magnet that points toward the Earth's geographic North Pole is labeled as the north pole of the magnet; correspondingly, the end that points south is the south pole of the magnet.\n\nThe Earth's current geographic north is thus actually its magnetic south. Confounding the situation further, magnetised rocks on the ocean floor show that the Earth's magnetic field has reversed itself in the past, so this system of naming is likely to be backward at some time in the future.\n\nFortunately, by using an electromagnet and the right hand rule, the orientation of the field of a magnet can be defined without reference to the Earth's geomagnetic field.\n\nTo avoid the confusion between geographic and magnetic north and south poles, the terms positive and negative are sometimes used for the poles of a magnet. The positive pole is that which seeks geographical north.\n\n\nCommon uses for magnets\nMagnetic recording media: Common VHS tapes contain a reel of magnetic tape. The information that makes up the video and sound is encoded on the magnetic coating on the tape. This is why magnets will destroy the information in these types of tapes. Common audio cassettes also rely on magnetic tape. Similarly, in computers, floppy disks and hard disks record data on a thin magnetic coating. \nCredit, debit, and ATM cards: All of these cards have a magnetic strip on one of their sides. This strip contains the necessary information to contact an individuals financial institution and connect with their account(s). \nCommon televisions and computer monitors: The vast majority of TV's and computer screens rely in part on an electromagnet to generate an image--see the article on cathode ray tubes for more information. Plasma screens and LCDs rely on different technology entirely. \nLoudspeakers and microphones: Loudspeakers actually rely on a combination of a permanent magnet and an electromagnet. A speaker is fundamentally a device to convert electric energy (the signal) into mechanical energy (the sound). The electromagnet carries the signal, which generates a changing magnetic field that pushes and pulls on the field generated by the permanent magnet. This pushing and pulling moves t

To answer your actual question - nobody knows.\n\nLike "charge", and "magnetism" it remains one of the fundamental mysteries of the universe.

1. Percentage is a ratio between two numbers times 100. Usually it is a part divided by a whole. To find a percentage we need both of these numbers. So the answer to your question I need to know which is the “non scientists who have no real clue of what electromagnetic pure energy is” and the other number to compute or even estimate the percentage.\n2. How does one compute purity of electromagnetic energy I have no clue and I pretended to work as a scientist for the past 20 years.\n3. And finally I have no firm idea about what gravity is and frankly what is pure energy. How ever I do know that if we have electrical charge in motion it will generate a magnetic field and magnetic field in motion will force electric charge to move. It seems that electricity and magnetism are products of the same electromagnetic phenomena.\n4. As far as gravity is concerned I do not know how exactly it relates to electromagnetism. Theory of relativity may provide some insight and there we may encounter some pure energy. \n\nI hope it was helpful.

Why do magnets work? \nMagnetism is an invisible force felt within the space around a magnet.  This space, called the magnetic field, can either attract (pull) or repel (push away) other magnets and some types of metal.\n\nAll magnets have two ends (poles).  These poles are opposites and are called the north and south poles.  Opposite poles attract, while like (similar) poles, repel.\n\nThe Earth’s core has its own magnetic field.  Magnetic north and south are near the geographic north and south poles.\n\nNASA has been experimenting with magnetic fluids for over 30 years. Magnetic fluids were made to help put fuel into a rocket engine. NASA was trying to solve the problem. of how to move fuel without gravity.  Tiny pieces of iron were put into the fuel. A magnet pulls the iron and could help get the fuel into the engine.\n\nMagnetic fluids are made by mixing pieces of metal in liquids to make a fluid that is very different from other liquids. It will stick to a magnet and can be directed by magnetic forces. Magnetic fields can shape the fluid, and magnetic fluids can change their thickness. They become hard around magnets.\n\nScientists have tried to use magnetic fluids to solve other problems. They’re used to make better computers. Scientists are still thinking of new ways to use the fluids.\n\nYou may use magnetic fluids!  Some cars have them in their shock absorbers. They are used in some buildings and bridges. The fluids help protect structures from damage from earthquakes or strong winds. There is still a lot to learn about these magnetic fluids. NASA is using the Space Station to learn more about them. They hope to find new ways to use them. \n\nKSNN thanks NASAexplores as a source of information.

Gravity is defined in a new term.  That is the latest report\n    of the atomic relativities of the quasar versus the quantum\n    in an isolated directive.  Defined by the mineral interactions.\n    What?  Gravity has the interactive quantities added to the\n    average force of one planet attracts to another Plus the ionic\n     pentanmeters(depends on the substance with conditions).\n    So gravity is present in all materials if left in free space, or put\n     into orbits, or put on a plane.  This last set is the theoretic\n     gravity of space infinitives to the nth degree, showing that all\n     materials have the origin of gravity values as established at\n     the desk of the elements chart, and its properties.  The flight\n     of planets is a true measure of gravities, showing such things\n     as anti-gravity points like in a space capsule.  The interaction\n      really never out drives the elements chart standard.

Neither,\n\nTheory is never proof so that's not it. Gravity is a weak force. M is an explanation why it is weak. Multidimensional theory is not about gravity, it's just part of it.\n\nEinstein tried to unify the fields, he failed. Many new theories came and went.... I'm not sure we 'got it' now. It is still a very unstable work in progress.

The theory is that gravity, or magnetism, moves at a certain speed.  The last I heard, that speed is still unknown but under study.  Thus, if the sun disappeared the earth would remain in orbit at the "speed of gravity"  and it would remain daylight at the "speed of Light."   Which speed is greater is yet to be determined.  However, my guess is that the speed of light is faster than the speed of magnetism.

Einstein alluded about forces saying that they are fictitious.This make sense because forces do not exist unless there is an interaction between two entities.\nThe magnetudes of interaction depends on the densities of the masses and their volume.The greater the densities the greater the interaction.Thus we can categorize them.\nHowever ;the mechanisms involved is the same in all interactions!Einstein Related this mechanism to a curvature.\nHe had discovered when a force comes into being it comes  from a common  mechanism(.A force is a force ). Force only come into being only as pairs.A force cannot exist by itself no more than a magnet having a single pole.\nUnfortunately ,He had the basis for a Unified Theory and did not realize it.\nAs far what has been measured in the interaction of micromasses or micromasses,I  dont believe there is anything exact.Only approximtions.\nThe phenomena of gravity apply to both micromasses as well as Macromasses.This is the only thing that is Realistic.\nIn other words Electrical phenomena as well Gavity are all one and the same Phenomena.\nYou may not agree with it but its a more realistic answer than resorting to the aphabetic soup of forces that the Physists have concocted as saying that they are different Phenomenae.\nIf you dont understand about their description of weak,strong nuclear forces, dont feel bad. I doubt that they fully understand it themselves!
