Iron better than steel in electro magnets?
Yes, they are.
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
Does the thickness or length of the nail affect the electro magnets strength?
yes
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
How are electro magnet like bar magnets?
a bar magnet and a electromagnet are alike in many ways. the are alike because both of them are magnets. but there are plenty other ways they are alike
Which magnets can retain their property for a short period of time?
Electro-magnets
Do magnets repel non magnetic materials not including electro-magnets?
of course not.
Why are magnets used?
Electro magnets can be very useful to carry heavy loads of iron and metal from one side of a factory to another. Electro-magnets are formed by shooting electricity through a coil of copper.
Are bar magnets stronger than electro magnets?
Yes, because electromagnets can lose their magnetism.
Are electro magnets sometimes called artificial magnets?
Yes, electromagnets itself is an artificial magnet.
Iron better than steel in electro magnets?
Yes, they are.
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 supply should be given for making electro magnets... ac or dc?
For a simple electro-magnet use a DC supply.
Does the thickness or length of the nail affect the electro magnets strength?
yes
What has electro magnets in them?
Lots of things do. For example, relays. (The electronical component)
