how to generate electricity with magnets?

THE EASIEST WAY TO DEMONSTRATE GENERATION OF ELECTRICITY IS TO GET SOME SMALL INSULATED COPPER WIRE AND WRAP IT AROUND A SMALL PILL BOTTLE,  AT LEAST 100 TURNS OR MORE (MORE IS BETTER) CLEAN THE INSULATION OFF THE ENDS OF THE WORE AND ATTATCH TO A VOLTMETER OR A MILLIAMETER.. INSERT A BAR MAGNET INTO THE PILL BOTTLE QUICKLY.  THE METER WILL GO ONE WAY WHEN YOU INSERT THE MAGNET AND WILL GO THE OTHER WAY WHEN YOU PULL THE MAGNET OUT.  THE FASTER YOU MOVE THE MAGNET THE MORE THE METER MOVEMENT.  HOPE THIS HELPS

The concept is to build an electromagnet that cuts the circuit when energised. This produce a buzzing effect

It depends on how powerful a magnet you use. To get a magnet to perform all of those tasks, it will need to be a really powerful one.

Electro-magnets use electricity to temporarily align all of the atoms in a ferrous material to a N-S position. When the electricity is turned off, the atoms return to their original misaligned state, losing much of its magnetivity. It never completely loses all of it, as some atoms will remain in the alligned state, creating a "Gauss" feild around it.

Generator generates electricity. It has a wire armeture mounted in an electic field. When the wire armeture is rotated, electric current is induced in the armeture du to change in magnetic flux.

Since you're dealing with a variable energy source (wind), you're best bet is to build a DC generator...\n\nIs this a science progect?\n\nA DC Generator is the same machine as a DC motor...  So if you're building something for your home, then just use a DC motor and a simple belt an pulley to reduce the rotational resistance (or load) on the blades, so a slower wind can be used...\n\nFor a Science project...  \nBuid three loops of wire and seperate them 60° on the rotor of the wind mill.  Place a magnet on either side. north to south\nSet up "brushes" (chunks of graphite like pencil lead) on either side so that as the rotor spins with the wind, the same side is going to the same terminal + or - no matter which side of the coil it is.\n\nHave fun with it...

you could sew flexible magnets into fabric. You may even be able to mount magnets into fabric like you would a button.  \n\nOK I GOTTA ASK... What are you making?

Technically a device that converts mechanical energy into electrical energy is usually called a transducer unless it is generating power at which point it is usually called a generator.\n\nSo a generator is a spinning magnet in a coil of wire. Spinning the magnet generates electricity in the coil. Examples of transducers include phonograph needles, sonar crystals, and BBQ grill lighters. These use a piezoelectric device to convert mechanical energy to electricity.

electricity is either made by chemical reactions, or by moving a magnetnic field over a copper wire, as i am sure you allready know, so the problem is geting a force that can move the magnet, to give inductance in the wire. causing a current to flow.\nwater turns the blades of a fan, or tubine whitch is conected to a magnet witch turns inside a copper coil.\nso any natural way that can generate enough force to move the magnet, can be used.\nwith nuclear the heat is made in a chamber called a reactor whitch turns the water to steam the steam turns the turbine whitch is conected to the magnet.\nif you have a propella connected to a magnet that is moved by wind that is driven by the sun, inside a copper coil you get some electricity\nin water fall the downward force of the water turns the blades, withch turn the magnet, inside a coil,\nall diffrent ways of doing the same thing.\nnot sure about forrest though, unless you burn the wood to make steam, to guess what turn the magnet inside the copper coil. or maybe you could cover the tree in magnets, and buld a copper coil next to it, then wait for the wind to sway the tree

Not just any A/C motor will.\n\nCurrent is generated by ,,"Waving a MAGNET past a COIL"\n\nUsing a NON-Magnet produces nothing.\n\nMost A/C motors do not have permanent magnets.\n\nA/C Motor's "magnetism" is typically created by the Supply Current---Electromagnetism\n\nA/C motors can be converted to generate,,but it's not so simple as just spinning the shaft of a DC motor or any permanent magnet motor.\n\nThere's stuff all over the net which explains what type A/C motor is easiest/best to convert,,and what's required.\n\nhttp://users.aber.ac.uk/iri/WIND/TECH/MISC/MotorsAsGenerators.html\n\nhttp://www.otherpower.com/otherpower_wind_alternators.html

An electric generator is a device used to convert mechanical energy into electrical energy.\n\nThe generator is based on the principle of "electromagnetic induction" discovered in 1831 by Michael Faraday, a British scientist. Faraday discovered that if an electric conductor, like a copper wire, is moved through a magnetic field, electric current will flow (be induced) in the conductor. So the mechanical energy of the moving wire is converted into the electric energy of the current that flows in the wire.The mechanical energy needed to turn the generator comes from the brown hand crank at the front of the generator. In a hydroelectric power plant, the mechanical energy to turn the generator comes from the water turbine, which is turned by the force of falling water. The hand crank causes the red wire to spin inside a magnetic field (the blue lines). As Faraday learned, moving the wire through the magnetic field causes electric current to flow in the wire. The turning red wire is connected to a volt meter, which shows the amount of electric current that is produced. In a hydroelectric plant, the generator is connected to transmission lines that deliver the electricity to your home or business.\n\nThe controls allow you to control the speed and direction of the generator and turn portions on and off for greater clarity. You can also use the radio buttons to show a direct current, or DC generator (with commutator) or an alternating current, or AC generator (without commutator).

Ferromags are substances that are strongly attracted by a magnetic substance. Some ferromagnetic  metals are iron, cobalt, nickel, gadolinium and dysprosium. To generate electricity from ferromags, take two iron sheets 5 cm wide. rub both of them using a bar magnet only in one direction for about 10 minutes. This will impart magnetic properties to d iron sheet. Then u arrange the sheets in such a way that u feel d force of attraction between the sheets. take a copper wire. make a loop out of it. rotate d loop in d space between d sheets with a constant frequency. Voila electricity generated at d ends of d loop

It sounds like you need a multi-meter which is handy for all your electric household needs. You can measure current with most of these and they can be found in hardware stores like Ace in most cases and possible even at places like Wal-Mart. They are not uncommon items. If you want you might be able to go online and search for a amp meter most likely from a physics teacher website. I'm sure your nearest hardware store will carry coil but if not, Radioshack is an option. Problem with Radioshack that I have had is too much money for too little quantity (this is in general and not specific to the coils) if you have time, you can browse the internet for teacher selling sites but you may have to pay for shipping which might also run up the cost. The magnets really depend on what scale you are talking about. Hobby Stores will definitely carry small craft magnets but if you need really strong magnets your best bet is once again a teacher website. I hope that I have been at least some use to you, and best of luck on your experiment/project.

A generator is a machine that converts mechanical power to electrical power, by making a conductor cut across a magnetic field's lines of force.  This is done by moving either the conductor or the magnetic field.  Current flows in the conductor if its ends are connected to an electrical load thus producing electrical power.  Because an opposing magnetic field is created by the current in the conductor, it requires mechanical energy to maintain this motion.

magnet \n\nAn object that attracts iron and some other materials. Magnets are said to generate a magnetic field around themselves. Every magnet has two poles, called the north and south poles. Magnetic poles exert forces on each other in such a way that like poles repel and unlike poles attract each other. A compass is a small magnet that is affected by the magnetic field of the Earth in such a way that it points to a magnetic pole of the Earth. (See magnetic field and magnetism.)
