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

∙ 14y agoYou could wrap a permanent magnet inside a coil of wire to generate an electric current, and then use that electric current to run an electromagnet. If a magnet were used as the core of an electromagnet, it would have to have the same pole orientation as the induced field, or they would partly negate each other. Some electromagnets demonstrate "remanent magnetism" where the core is slightly magnetic for some time after the current is switched off.

∙ 13y agoAn electromagnet is composed of a power source (battery) and a wire. When current flows through the wire a magnetic field is generated around the wire. Such a magnet can be used to run motors or light a light bulb. An electromagnet is similar to a refrigerator magic except an electromagnetic only has magnetic qualities when there is current running through the wire.

∙ 10y agoA magnet has a magnetic field. In fact, a magnet, by definition, is an object which creates a magnetic field.
A magnet may be a solid object which we could call a permanent magnet. A magnet may also be created by an arrangement of wires carrying and electric current and we call that an electromagnet.

Why electromagnet is different from a permanent magnet because an electromagnet what?
Mainly in that the electromagnet is NOT permanent. In other words, it can be switched on and off.Another relevant difference is that the electromagnet constantly requires power, at least while it is on.
What will be attracted or repelled by a magnet?
An aluminum wire carrying current An electromagnet An iron pipe (Apex)
What is a lifting magnet?
A lifting magnet is an electromagnet that is meant to hold or move material that comes in contact with the magnet. This is the opposite of a traction magnet.
How do you turn off an electromagnet?
This is what makes a magnet an electromagnet - the ability to turn it on and off... Anyway, electromagnets can be turned off with either the help of a switch, or just by disconnecting the power supply.
Why does a magnet work under water?
Interesting question. The answer is maybe - it depends on the construction of the electromagnet. the key is the electromagnet must be water proof, and the wiring used to create the magnet must be insulated from water - if this is not done, then current will flow through the water, which will decay the effectiveness of the electromagnet, along with robbing it of strength due to a decrease in current through the magnet.
How is an electromagnet different a bar magnet?
a electromagnet is bigger than a bar magnet
Which is better a permanent magnet or an electromagnet?
electromagnet
Which type of magnet is created from an electromagnet?
a temporary magnet can be created by an electromagnet but it can also be created by any type of strong magnet
How is a electromagnet diffrent then a permanent magnet?
By definition an electromagnet is only working when it has a supply of electricity, a Permanent Magnet is always a magnet
Is a permanent magnet called a hard magnet or a electromagnet?
Perminant magnet
Is the worlds biggest magnet a magnet or electromagnet?
the world is
What is a magnet made by electric current?
An electromagnet.
Is electromagnet a permanent magnet?
no
Why will an electromagnet be able to pick up more steel cans than a permanent magnet?
An electromagnet is a stronger magnet.
Is a horseshoe electromagnet bar magnet or a magnet pole a example of a temporary magnet?
An electromagnet is temporary because the field disappears when the current is switched off.
The space around a magnet where the force of the magnet acts is a?
electromagnet
An advantage of an electromagnet (in contrast to a bar magnet) is?
An electromagnet can be turned on and off.
