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 is an electromagnet similar to a magnet?
The reason is because an electromagnet is hooked up to an artificial energy force, while a magnet is a charged piece of metal example: a battery hooked up to a piece of iron attracts paperclips but a magnet can be made by stroking a paperclip against a bar magnet to create a temporary magnet somewhat how a compass works
What are some temporary magnet example?
some examples are paper clips and iron nails,
Explain how a metal can become a temporary magnet?
Real quick FYI, temporary magnets are also called electromagnets :) A really simple electromagnet is an iron nail with with copper wire (can be insulated or uninsulated) wrapped around it. At the ends, attach a 9-volt battery to the negative and positive terminals. And voila! To "turn-off" the magnetism, just remove one of the ends from the terminal.
How do you test if something is a magnet?
Get a randomn piece of iron and put it next to the magnet. Hope this helps someone.
How are temporary magnets different from permaanent magnets?
temporary magnet permanent magnetit stays for a little while it stays foreverit is made from iron it is made from steel
What is a temporary magnet?
a temporary magnet is a piece of soft iron that is magnetized while in the presence of a magnetizing field but demagnetizes the moment the iron is taken away from the magnetizing force
What happens to the iron ruler if it rubs with a magnet?
It will become an electro-magnet which is an temporary magnet. it is because of the induction property, the magnetic effect gets transfered to the Scale. (it can be any piece of Iron)
Is magnetite a temporary magnet?
No, it's a permanent magnet. It consists of an iron oxide, and iron is a permanent magnet.
How can you turn a piece of iron into a magnet?
To turn a piece of iron into a temporary magnet, wind a coil of (insulated) copper wire around it and run a DC current through the wire. The iron will become the core an electromagnet -- the one you just constructed. As long as direct current flows through the coil, the iron core will attract ferromagnetic materials.jkghyjy Wrap many coils of lacquered copper wire round an iron nail. When electricity is sent through the coils, the nail becomes magnetised. The iron is an electromagnet as long as the power is on. When a piece of iron is brought near the magnet it also becomes a temporary magnet.
When a piece of iron behaves like a magnet when it is touching a permanent magnet that is called?
The process by which a iron piece touching a permanent magnet behaves as a magnet as long as it maintains contact is called magnetic induction. not only does this work when the iron is physically touching the magnet but it works as long as the piece of iron remains under the influence of the magnet. A iron piece attracted to a magnet through a paper with out any physical contact will also behave as a magnet.
A magnet attracts a piece of iron and the iron can then attract another piece of iron .What is the basis of this attraction?
When an iron piece is quite away from the magnet ,i.e, not present in magnetic field of the magnet then the iron piece is in neutral state ,i.e, there is no north & south pole . But , as soon as the iron piece interacts with magnetic field of magnet ,i.e, near to the magnet then the north pole of magnet make the nearer part or end of the iron piece south pole & simultaneously other part of iron becomes north pole . Similarly if south pole of the magnet interacts with iron piece then that end/part becomes north pole & other end becomes north pole . Now this iron piece has north & south pole .So iron piece is now converted into magnet which can attract other iron pieces in similar way as explained before .
What type of magnet attracts to iron but not for a long time?
Bar magnet. Because a bar magnet is strong to iron..... Or that's what we did in class.....
How do you make temporary magnets?
There are basically two ways to make temporary magnets. They arethe stroke method and the electrical method.The Stroke Method:Take a piece of metal like iron and stroke the magnet across it in a certaindirection I.e. in a straight line. Keep stroking the magnet across the iron piecein the same direction for a few more times. The piece will be slightly magnetized.The Electrical Method:Wrap an iron bar with a coil, a conducting wire of copper, and connect the ends of the wire to the terminals of a battery. Electricity will pass through the bar which will result in the formation of an electromagnet.
What are the three uses of a temporary magnet?
a magnet that remains magnetized for only a small time interval as compared to a permanent magnet.
How can a temporary magnet be made from a ferromagnetic material?
Yes, you will create a temporary magnet. EX: if you put and nail next to an iron magnet, the nail will be temporarly magnetic.

Give example of a temporary magnet?
when a magnet is hardly rubbed on a iron ,for some time it reacts as a magnet. An example of a temporary magnet is used in acar breakers yeard . A crane fitted with amagnet picks up a car and then the power to the magnet is cut and the car drops.
