How can you tunna piece of iron in to a temporary magnet?
Wrap the iron with many turns of insulated copper wire. Then send a current through the wire. The iron core will become an electro-magnet while the electricity is running.
How do you make a electro magnet with a wire and a nail and electricaty?
you dont make it. ull save time. you're welcome...
What are the benefits of using an electromagnet rather than a bar manet?
An electro-magnet can be switched on & off - a bar magnet is 'permanent' Think of a scrap-yard. If the magnet they use to pick up huge quantities of metal were permanent, they'd have to manually remove every piece. With an electro-magnet, they simply turn the power on to pick up a load, and off when they want to release it. You can make your own electro-magnet with a battery, some wire and a large nail.
How are electromagnets formed?
A magnet consisting essentially of a coil of insulated wire wrapped around a soft iron core that is magnetized only when current flows through the wire.
How do you make a solinoid magnet?
Get a piece of soft iron (a piece of mild steel will do), and wind some insulated copper wire around it. Check the resistance of the coil of wire to make sure you have a suitable power supply (use V=IR), and apply a current - job done.
How can you tunna piece of iron in to a temporary magnet?

What is produced whencoiled wire is spun around a magnet?
An electro magnet!
What is a magnet that is creadted from electric current through a wire?
Electro-Magnet

What materials do you use to make an electro-magnet?
an iron nail, a long peice of wire, a large battery or a transformer
How do you make a single negatve pole electro magnet?
Wrap copper wire around a nail, then attach the ends of the wire to a D battery with tape to make an electromagnet.
What happens if the insulation is removed from the copper insulated magnet wire?
No it does not attract to magnets
How are eltromagnets used in generators?
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" :)
What are the three important parts of electro magnet?
Battery/iron rod/copper wire.

Is a permanent magnet needed to make an electromagnet?
no you just need something metal like an iron nail and wrap a coil of un-insulated wire around it and send a current through the wire.
Why does an iron nail behaves like temporary magnet if insulated copper wire is wound around it?
which end of a magnet will pick up an iron nail?
