Actually paper does interact with magnetic fields.  It "hinders" the magnetic field.  I am referring to the ease with which the magnetic flux can pass through a substance.  Everything has a such a value.  It is comparable to the dielectric constant in capacitors.  Metals pass magnetic fields fairly readily though there is some difference even between the metals.

Only magnetic force that breaks thru the coil field will produce electricity. you can take a old electric motor and spin it and it will generate electricity. but if you remove on magnet it will not produce. place the magnet on the out side and it will not produce. it has to make a force between the fields. it is the disruption of this force and the coil fields that produce electricity.

There are a couple of naturally occurring ferromagnetic substances, like magnetite (Fe3O4) or nickel-iron from comets, which can act as permanent magnets. The metals iron, nickel and cobalt all exhibit ferromagnetism and can be magnetized. Oxide minerals from these elements may be ferromagnetic, too.

MAGNET THATS POWERED BY ELECTRICITY

The exchange of electrons between atoms, making atoms have a charge, which creates magnetism. Depending on the direction of the spin of the electrons around the nucleus, if an unequal amount of electrons spin in two different directions, there will be magnetism. \n\nMagnetism is also created by running an electric current through a particular substance, electromagnetism.\n\nAll materials have magnetism, but most are in a very minute amount.

Well even though humans have known about magnets for thousands of years, the real reason they work is still somewhat mysterious. Depending on how deep you want to investigate, it can be a very complicated phenomenon. \n\nA magnet is, at its foundation, caused by the movement of electrical charge (yes this is the Biot-Savart Law). When charges (like electrons for example) move, they produce magnetic fields. If a charge moves in a loop, it creates a magnetic field. The magnetic field can be basically represented by an invisible set of arrows in space, that point in a direction. In the case of the loop, the arrows of the magnetic field will point out of the loop for a positive charge moving counter clockwise (this is the so-called "right hand rule"), and into the loop for a charge moving clockwise (some pictures are in the reference attached). \n\nThe magnetic field has a "north" end and a "south end". The little arrows from our moving charge are pointing in the "north" magnetic direction, and away from the "south" magnetic direction. It is a mysterious and interesting property of electromagnetism that two objects with fields that oppose each other, i.e., the little arrows of the field do not line up, so either the north end of one field is facing the north end of the other field, or the two south ends are facing each other, repel, or resist movement of the two objects towards each other with some force. \n\nOn the other hand, if the little arrows line up, the two objects attract each other with some force. \n\nThe forces that result from magnetic fields (and for that matter, electric fields) are fundamental forces, and part of the four fundamental forces of the universe (strong, weak, electromagnetic and gravity).  It is believed that these forces are caused, at their base, by particles passing "messenger particles" back and forth. In the case of electromagnetism, the messenger particle is a photon. How this actually works is still somewhat poorly understood, and is involved with the world of quantum mechanics, which is very counterintuitive but interesting. \n\nHowever, what is important is that we understand it well enough to make models of magnetism, and to make predictions based on those models which we can verify and use. All of electricity and electric motors are based on our ability to design systems with magnets and to be able to build and use them.

By behaviour of magnetic field associated with any electric conductor, the field is at right angle to the direction of flow of current. Means if current flows along X Axis, magnetic field's plane lies in YZ plane.\n\nVice a versa, if changing magnetic field is in YZ plane and a conductor is placed in the area of influence of field, current is induced in the conductor which flows in the direction of X axis. Well, these are basics.\n\nIn any magnetic device like transformer, motor or choke this principle is used. To strengthen the magnetic field, magnetic materials such as Iron cobalt etc are used. Electric conductors are arranged in these devices in such a way that magnetic field produced by electric current is at picked up by the magnetic material which are called as "Core". When magnetic field produced by electric current, magnetizes this core and the current causing the field is "Oscillating" the magnetic field associated with current also oscillates. The core material whether it be Iron or Cobalt, is a metal. It may not be as good a conductor of electricity as copper or silver or gold, but it is a conductor and not insulator. This oscillating field within the core produces induced current within the core itself.\n\nSince any electric current flow finds the shorted least resistance path, this induced current circuit closes in a small loop and in this process many small loops of current are formed in the core. This is similar to circulating air in a whirlpool or eddys prodcued in the water when you drop a stone in the water. Hence these current loops are called Eddy Current.\n\nThese small loops of current, circulating in small circles cause heat to be developed which heats up the core. Since there is also a magnetic field associated with these current loops, and is in opposite directiont of the main field, it results in reduced magnetic field density etc etc.\n\nHowever, in induction heating furances this unwanted phenomenon is put to use.\n\nIs my answer just that what you are looking for?

Ferromagnetism is the phenomenon that deals with three metals: iron, cobalt, and nickel.  These metals have unpaired electrons in their valence atomic orbitals and thus form a small magnetic field (the region that encompasses this magnetic field is called a domain).  A piece of one of these metals, however, has all of its domains oriented in several directions and thus there is very little net magnetic field.  When these metals interact with an external magnetic field, however, the domains all align in the same direction, thus causing these these metals to have magnetic properties.

I guess it can be magnetized. I don't think there would be any problem even if its in the form of a moebus strip, or any form at all. Anyway I am curious for other answers.

Yes, this is the principle that motors work off of.  It is also used for other purposes, such as launching roller coasters.  While it is possible to control the strength of the magnetic field in an electromagnet, permenant magnets cannot have their fields controlled.  So, in order to control the force between two magnets, only one of them must be controlled, so one may be an electromagnet and the other a permenant magnet.

It lacks the crystalline electron structure that elements like magnesium and iron have. Thus, it cannot align into electrical dipoles, and is not magnetic.

Electromagmetism is one of the four fundamental forces of nature (the other three are gravity, the strong nuclear force, and the weak nuclear force.)  Electromagnetism acts only on charged particles (e.g. protons, electrons).  Electromagnetism has the ability to act over infinite distances.

Antigravity, but that hasn't been proven.  Magnetism works when you have two magneticaly charged objects.

Electromagnets are made out of metal that can easily be magnetized by applying DC voltage. Electromagnets do not occur naturally in nature but are manmade. Their magnetism can be turned on and off.\n\nPermanent magnets occur naturally in nature.

Try this. Iron when combined with other metal elements becomes non-magnetic, yet with varying of the same elements is quite attracted to the magnet.Name the divisions of the metals and explain why.

Large commercial generators do not have permanent magnets. The rotating field is magnetized via slip rings that feed current into it's windings. The current is generated by the exciter which is either a small generator attached to the end of the shaft or, in modern applications, an electronic SCR converter.

Paramagnetic materials like Aluminum have magnetic properties, but cannot sustain a permanent dipole moment alignment. Hence it qualifies as a candidate for your question.\n\nAlso ferromagnetic materials (common ones are Cobalt, Iron, and Nickel) above their associated curie temperatures behave the same way. No permanent magnetization.
