Okay - it's going to be difficult to do an accurate diagram on here - so bear with me...
An electromagnet consists basically of a piece of metal surrounded by a coil of wire, which is connected to a power source. The simplest form would be an iron rod which has a piece of wire wrapped around it (about ten) coils should do it. The ends of the wire are attached to a 9 volt battery.
Ignore the dots in the following diagram - they're just to stop the spaces being removed by the forum !...

It's a bit crude - but I think it's understandable. Basically, you connect the battery (+ -) with a continuous piece of wire. Wrap the wire around an iron rod - the '/\/\/\'. This induces a current in the rod, while the power is connected. Snakester1962 (Supervisor)

∙ 12y agoit is very simple
all you need is a peice of metal preferable a nail or a metal bar
then you coil a copper wire around it and the at the end you will get to ends of the wire at the end, just attach the 2 ends to a battery.
and there ladies and gentle men you have made your elctromagnet.
(it works)

∙ 8y agouse a solenoid----that is, a coil of wire wrapped around a magnet. When you wave the magnet through the coil of wire it will produce electricity (a small ammount) through the wire

Why electromagnet is different from a permanent magnet because an electromagnet what?
Mainly in that the electromagnet is NOT permanent. In other words, it can be switched on and off.Another relevant difference is that the electromagnet constantly requires power, at least while it is on.
How do you turn off an electromagnet?
This is what makes a magnet an electromagnet - the ability to turn it on and off... Anyway, electromagnets can be turned off with either the help of a switch, or just by disconnecting the power supply.
The strength of an electromagnet only depends on the current in the coils?
And the amount of coils.
Is there a magnet in an electromagnet?
An electromagnet is a type of magnet in which the magnetic field is produced by the flow of electric current. The magnetic field disappears when the current ceases. Take a look at this Wikipedia page for more information: http://en.wikipedia.org/wiki/Electromagnet

Which is better a permanent magnet or an electromagnet?
electromagnet
Strong temporary magnet formed when a current is passed through a coil of wire?
A magnetic field.
What is the structure of the magnet?
"Structure" is an imprecise term. So is "magnet," for that matter. The simplest kind of iron bar magnets have a structure of, well, iron. More complicated rare earth magnets generally have a more complicated crystal structure, but still, there aren't any "moving parts" inside a magnet, it's just whatever it's made of. The structure of an electromagnet is basically "wire wrapped around a metal core of some kind". The core isn't actually required, but all else being equal an electromagnet with a soft iron core is stronger than one with no core.
