According to Maxwell's laws, one type of field can induce the other and vice versa. This makes electromagnetic waves possible.

Magnetic flux is measured in Webers.\nLooking at the link below, we can translate Webers into other units:\nWebers = Volts x seconds\nWebers = watts/amps x seconds\nWebers = joules/seconds/amps x seconds\nWebers = joules/amps\nor an amount of energy per unit current.\nMagnetic field strength is measured in amps/meter:\nthe more amps, the more field strength\nthe farther you are from the wire(s) generating the magnetic field, the less field strength\n\nIf you consider Einstein's equations, Maxwells' equations, and the Lorentz transformation, then you see that a magnetic field can also be thought of as what an electric field looks like when you move past the electric field as very fast (appreciable percentage of speed of light) speeds.

E=MC2 describes the potential energy in all matter. Since C is the speed of light, and C squared is a HUGE number, there is lots of potential energy stored in all matter.\n\nThere isn't really a practical application unless you're building an atom bomb or a time machine.

ok, well, let's start with a basic description of magnetic materials.\n\nmagnetism has to do with the way electrons in a material interact with each other.  electrons have some basic properties (mass, charge, for example) and also a property called "spin".  \n\nit can be measured that any given electron has what is called a "magnetic dipole moment", which basically means that every electron behaves like a tiny bar magnet.  so the property of "spin" was devised to explain this - if you have some electric charge and move it around in a closed loop, a magnetic field is generated inside the loop.  this phenomenon is called induction and it's the basis for lots of real-life magnets.  this is why you usually see electromagnets made by wrapping wire around in a coil - when you pass an electrical current through the wire, the electrons in the metal basically move in a loop, and this causes a field to form.\n\nanyway, you can think of an electron as a little ball of electrical charge.  if the ball is spinning, then the charge on the ball is moving around in a circle - so this would create a magnetic field.  \n\nanother measurable property of this "spin" is that it is quantized - this means that the electrons can only spin at certain speeds and orientations.  different particles have different spins, and for an electron there are 2 spin states - usually referred to as "spin up" and "spin down" because the axis of the dipole moment points in different directions.\n\nthe difference between the various types of magnetic materials (ferromagnetic, antiferromagnetic, paramagnetic, etc) is in how the spins of all the electrons in the materials are oriented.\n\nin a ferromagnet, the spins are (mostly) oriented so that they're all pointing the same direction.  this causes the magnetic fields from each electron to add up, and you get a large macroscopic magnetic field as a result.\n\nin an antiferromagnet, on the other hand, spins are oriented so that neighboring electrons point in opposite directions.  this is a highly-ordered state, and in many materials only forms when you cool the substance below a critical temperature called the "neel temperature".  above this temperature the random thermal fluctuations take over and the spin ordering falls apart.\n\nantiferromagnetism is observed in transition metal compounds, in particular metal oxides, such as nickel oxide (NiO) or cobalt oxide (CoO).  the behavior of electronic spins are a subject of intense research these days, and so a simple and well-defined picture of their behavior is not easy to come by.  \n\nhowever, it is thought that the long-range interactions of electronic spin is responsible for a number of interesting effects that are being studied in transition-metal oxides.  one well-known example is in the study of high-temperature superconductors, which are often oxides of transition metal alloys.  the electrons involved in the superconducting effect act in pairs called "strongly correlated" electron pairs, and it is thought that the electrons interact via coupling through their spin.\n\nhere are some links so you can learn more:\n\nhttp://ghmfl.grenoble.cnrs.fr/magnetisme/recent5.htm\nhttp://www.jhu.edu/~gazette/2002/30sep02/30magnet.html\nhttp://www-als.lbl.gov/als/science/sci_archive/peem_spin.html\nhttp://en.wikipedia.org/wiki/Antiferromagnetism

Hi,\n\nYou know that if electricity is apllied to a coil over a magnet it causes mechanical movement due to the formation of magnetic fields similarly the converse is also true\nthat if mechanical energy is applied to a similar but reverse arrangement electricity can be produced\n\n\nwhen current flows magnetic fields are induced but if a fluctuating magnetic field forms in a ciol electricity is induced

When a magnet is passed through the centre of a coil of wire an electric current is produced in the wire. The energy comes from the movement of the magnet. Kinetic energy is converted into electrical energy and this is how electricity is generated in a generator. The reverse can also happen. Passing electricity through the electric coil in your cars starter motor will cause the magnet inside to move. Hence electrical energy is converted to kinetic energy and this energy turns the crankshaft of your car to get it started.

The inductor stores the energy in electromagnetic form. The capacitor stores it in electrostatic form. The resistor while dissipate it in heat form.\nIn an inductor when electric current is flown the magnetic field is formed in the coil due to Ampere'law. The magnetic domains in the core material are aligned accoring to magnetic field of coil. This takes energy from elctric current flowing to align themselves and is stored as magnetic enrgy.\nIn Capacitor when it is connected to a voltage source, the charges flow in to its large area electrodes to build an electric field across the insulator between electrodes. Here also the electric energy is stored in the insulator to align its dipoles according to electric field.\nIn resistor the current flowing increases the vibration of molecules of material as there are less free electrons to support current flow.

Yes, if it's converted to energy.  E=mc^2

The previous correspondent confirmed that only a moving charge is affected by a magnetic field, but didn't actually address the question of *why* that is the case.  I will attempt to do so.  First, realize that electric fields  and magnetic fields are, under the theory of special relativity, two interrelated aspects of the same thing. Like momentum and energy, or space and time, they vary, depending on the reference frame of the observer. The values for the electric and magnetic fields in one reference frame can be transformed to the values for another reference frame by using the Lorentz transformation.\n\nNow, imagine a charge at rest in a given reference frame.  It exerts a force on other charges given by Coulombs' law.  The amount of force it exerts on those other charges depends only on the amount of charge each of our charges has, and the distance between them.  Another way of looking at this is to say our charge sets up an electric field, and the force on the other charges depends only on the strength of the field and the amount of the other charges.\n\nNow imagine that we are looking at this charge from the point of view of a reference frame that is moving with respect to the charge, so that to us the charge appears to be moving.  We take the formula for the force exerted by the charge, apply the Lorentz transformations which we have to use to relate quantities in different reference frames, and lo and behold, we not only get a force that depends on the amount of the other charges, we get a term that depends on the relative velocity of the charges.  What's more, the force of this new term is at right angles to the relative motion.  We identify this new part of the force, the part that depends on relative velocity of the charges, as the magnetic force.  Hence, the magnetic force depends on the relative motion of the charges.

The energy isn't destroyed, but it is reorganized into different forms.  Think of it this way: Imagine you have a bunch of fridge magnets with words on them, and you arrange them into a brilliant poem.  When you come back later, someone else has rearranged the magnets.  All of the magnets have been "conserved"-- they're still there, and they're just as magnetty as ever-- but the particular shape that they were in when they were your brilliant poem is unrecoverable.  Sorry. <3

The energy is stored in the magnetic field of the coil. There are no other things to store in the coil. “The energy stored in an inductor” is the short form of saying “The energy stored in the magnetic field”.\n\nSimilarly, the energy stored in the condenser means, “The energy is stored in the electric field”.\n\nThe energy stored in a coil can be calculated using, inductance and current. It can also be calculated independently using magnetic flux and volume of the coil. Both are one and the same energy.

No common denominator for the energy in the things you mention except that if it has mass, then it embodies the energy given in E = mc^2\n\nThis applies to ALL matter.

Electricity is a form of energy . Energy can't be created nor destroyed . If you are talking of using a small electrical signal to make a large electrical load to work ...Ex : a 50 HP motor at 480 volts starting and running with a 24 volt 1 amp signal application ...that would be done through electro magnetic contactors in which a small 24 volt 1 amp source is applied to a coil and closes the contactor to permit the much larger source ( 480 volt + / - 70 amps ) to cross and energize the load ( 50 HP ) motor ....If you talk of generating electricity there are several ways but can't be considered " amplifying " in the true sense of the word...Hope I clarified this point for you ...

Magnetism is an inherent property of a material or object, e.g. the earth.\n\nElectromagnetism is magnetism created by an electrical field - electromagnet - and these can be found all over the place - electrical relays, doorbells (check yours you will almost certainly find that it contains an electromagnet, etc.\n\nIn most cases when the current is turned off the electromagnetism goes.  However, it is possible to magnetise something permanently by use of electromagnetism.

I had the same problem when I learned about both of them. \nBut now think of it in a different way. You are assuming that the magnetic FORCE that magnets have on certain metals. But if you think about it carefully they don't create or destroy energy. \nIf you don't beleive me consider a piece of iron with only gravity working on. But its height is 0 so it has no Potential or Kinetic energy. But now let's say you bring in a magnet. Now naturally that will make the iron bar rise and stick to the magnet. Now a natural assumption would be that you just created potential energy because the height of the iron bar just increased. But now you have to consider the fact that magnet is still putting some force on the Iron bar. So no change in potential energy occured. No change in Kinetic energy occured once the bar stuck to it. and the Energy needed to bring the bar up could be accounted by the energy needed to bring iron bar in. This shows that there was no energy created.  \nI think that you are trying to overthink the problem. I think this should help good luck.
