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
Is the worlds biggest magnet a magnet or electromagnet?
the world is
Is a permanent magnet called a hard magnet or a electromagnet?
Perminant magnet
What is a magnet made by electric current?
An electromagnet.
Why will an electromagnet be able to pick up more steel cans than a permanent magnet?
An electromagnet is a stronger magnet.
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
An advantage of an electromagnet (in contrast to a bar magnet) is?
An electromagnet can be turned on and off.
What is a magnet that can be turned off?
An electromagnet.
What is the difference in a common bar magnet and an electromagnet?
The comon bar magnet has two poles, and the electromagnet can be turned on and off also the electromagnet uses electricity to create a magnetic field in the first place. so the difference is normal magnet cant be turned on and off but the electromagnet can. does that answer ur question?
Is electromagnet a permanent magnet?
No, an electromagnet is not a permanent magnet. It is a magnet that produces a magnetic field when an electric current is passed through it, and the magnetic field disappears when the current is turned off.
What is different about an electromagnet compared to a regular magnet?
An electromagnet is different from a regular magnet because it can be turned on and off by controlling the flow of electricity through it, while a regular magnet is always magnetic.
