When would you want to use an electromagnet rather than a permanent magnet?
When you need a magnet you can turn on and off an electromagnet is used.
Would an electromagnet be attracted to a magnet?
Yes electromagnet would be attracted to a magnet provided direct current flows through the coil ie when the electromagnet is activated. As unlike poles attract each other the magnet is to placed accordingly. Otherwise repulsion would take place.
How would you separate nails from flour?
To separate Nails from flour you would get a magnet and put the magent above the bowl of nails and flour. The nails will then be attracted to the magnet and then you will have the nails separated from the flour.
Can magnets attract iron filings?
Yes A magnet would help you separate a mixture of iron nails and iron screws because the magnet when you wave it over the iron nails it will pick them up and then you just wipe them off the magnet with a paper towel and then your iron screws are separated Answer: NO!!!! The magnet would pick up nails and screws equally if they were both made of iron and were the same weight. A magnet would pick up something lighter more easily, but unless all of your nails were one weight and all of your nails were another weight, the magnet would not be able to separate them.
Would increasing the length of a rod in an electromagnet increase it's magnetism?
No, as in this case,the rod is the magnet,and the strength of a magnet does not depend on its size.
How would you separate steel nails and brass screws?
With a magnet.
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
What will happen if you put a compass next to a electromagnet that is turnd on?

Why would electromagnet be used in a recycling yard rather than a strong permanent magnet?
Because with an electromagnet, you can turn it off and on - you can pick things up with it then drop them again.
What suitable material would you use for the core of an electromagnet?
Iron - use a bunch of iron nails, wrapped many times with insulated copper wire, if making your own electromagnet.
Why would a nail be attracted to a magnet?
if a nail has any iron in it, it will be attacted to a magnet. Most nails are made of steel, a substance created from iron.
Why are electromagnets used instead of a permanent one?
sometimes in magnetic sepration etc electromagnets are more useful than permanent one as first magnet is used to seprate metallic waste and then its turned off so that attracted waste falls off at desired place so here permanent magnets are not that use full as electromagnet as in permanent magnet waste would get attracted but it would not fall. so electromagnet is more useful than permanent one.
