Electro magnets differs from permanent magnet because it requires electricity. A simple electro magnet consists of an iron rod wrapped in a coil of copper and when electricity flows through the copper, a magnetic field is formed.

Why would a bar magnet pick up more paper clips than an eletromagnet?
?? lol i dont know what electro magnets u have been using! if it is a homemade electro magnet, try increasing the coils in the wire ro the power u are putting into it. does the bar magnet (permanent magnet) have a larger surface area than the electro one? also, you do know that the magnetic potential of electro and permanent magnets vary right? they use electro magnets in junk yards that are capable of lifting scrap cars with eaaase
What is an example of a situation where it would be best to use certain types of magnets to attract different types of objects?
Electro magnets can be used to attract metals temperarily while permanent magnet would be used for compasses.
How are electro magnets different from other magnets?
An electromagnet can be turned on and off, with an electric current and a magnet can not turn off
What magnet do you use to purify water?
electro magnet or a very high powered magnet i no this because i am doing a science projet on this
What c is the piece of iron inside an electro magnet?
Core
What is the strongest type of permanent magnet?
An electro-magnet would be the strongest magnet. Or the sun itself would be the strongest natural magnet.

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 temporary and permanent magnets alike?
Yes Permanent magnets is the term used to describe magnets that are always magnetic, an non permanent magnet would be an electro magnet which is only a magnet when an electric current is put through it.
When all of the magnetic domains line up on their own what is the materia called?
electro magnetic feilds
What are the uses of electro magnet?
The most common uses of an electro magnet begin with the harnessing of electricity in windmills.
What is an example of a situation where it would be best to use certain types of magnets to attract different types of objects?
Electro magnets can be used to attract metals temperarily while permanent magnet would be used for compasses.
What does the electro magnet prove about electricity?
An electro magnet proves that Electricity and Magnetism always co-exist in nature
What magnet can be switched on and off?
An electro-magnet can be turned on and off.
How are electromagnets different from permanent magnet?
You can turn electromagnets on and off.
Compare an electromagnet and a permanent magnet?
See compare and contrast permanent vs. temporary magnet. Unless, of course, they are truly two different questions.
Electro magnet used for?
A electro magnet is used for lifting things by the magnetic force provided by the amount of coils and the size of the battery
