There are magnetic fields around a magnet that form closed loops. Although you can't see these fields there existence can be observed by taking two magnets and seeing that they pull themselves together when opposite poles are placed next to each other or push themselves apart if like poles are brought together.
If a wire is simply sitting next to a magnet then no voltage potential will be created in the wire. For a voltage potential to be created the wire (or the magnet) must physically be moving. Specifically it must be moving as a function of time. As long as the wire moves through the field around the magnet a voltage potential will be created. This process is described by Faraday's law of induction and is the basis for all modern generators. For generators to work the generator must be turned which causes the wire within it to cut across the magnetic field.
NO. Magnets need some other energy source to move. Yes it do, that is how electric motors work, as long as an AC current is applied to the coil
Yes. That peculiar action weill create a current in the coil for as long as you keep the magnet moving.
... exhibits a voltage between its ends. If there is a conductor between the ends of the coil, then a current flows in the coil.
1/2 true, when moved though a wire coil electricity is formed.
Electricity is made when a magnet is spun round quickly inside a tube with a wire coil raped around the inside of the tube this is used in a electric power stations, dams ect.
Yes.A moving magnet inside a coil of wire creates electricity, however, a magnetic flux is produced by an electrical current. Many experiments are described on the internet regarding a current and iron filings to determine the magnetic flux.
Yes. That peculiar action weill create a current in the coil for as long as you keep the magnet moving.
No. Magnets create an electric feild, not electricity.However, when you spin a magnet inside a coil of wire (or you can spin the coil of wire instead), you will create an electrical current.
A spinning magnet inside a coil of copper wire will produce electricity.
The standard way of generating electricity is moving a wire coil through a magnetic field. So yes
a magnet moved through a copper coil makes electricity
yes

An electro-magnet is th aswer. Hey STOP CHEATING ON YOUR HOMEWORK AND CHECK OUT MY YOUTUBE! it is ....... http://www.youtube.com/nickjonasfan910
If you have a coil of wire and pass a magnet trough it it will generate electricity in the coil. Similarly if you put a magnet in a coil of wire and pass electricity through the coil the magnet will move. An electric motor operates on the second principle - a rotor fitted with coils of wire is placed in side a cylinder formed from magnets and electricity is passed though the wire coils (from attachments on the rotor called brushes) and the rotor is made to spin. If however you take the same motor and mechanically spin the rotor then the reverse happens and electricity is generated - the motor becomes a dynamo.
Any time a magnet passes through a coil of copper wire (the electro magnet) it produces electricity. In all reallity, you don't really have an electro magnet in a generator. Since the Coil or(field) is making the electricity instead of using electricity, the electro magnet isn't really a magnet; but more like an "anti-magnet" :)
