An magnet is a material or object that creates a magnetic field. Bar magnets constantly create their magnetic field, while electromagnets are coils that only produce a magnetic field when an electric current passes through it.

∙ 11y agoAn electromagnet is a magnet controlled by the electrons shifting inside it, so when an electrical current goes through it, the electrons align and it is magnetized A bar magnet is just a piece of metal that has been magnetized meaning the atoms inside are permanently fused in the aligned. An example of a Electromagnet would be a crane at a junkyard, who has a electromagnetic disc on the end of the crane to pick up large pieces of metal. An example of a bar magnet is refrigerator magnet.

But bar magnet is a permanent one.

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
How are electro magnet different from permanent magnet?
Electro magnets differs from permanent magnet because it requires electricity. A simple electro magnet consists of an iron rod wrapped in a coil of copper and when electricity flows through the copper, a magnetic field is formed.
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
Is a bar magnet magnetic?
A bar magnet is a magnet of rectangular shape with a north and and south end, which are sometimes coloured different colours to indicate which end is which.
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 are the benefits of using an electromagnet rather than a bar manet?
An electro-magnet can be switched on & off - a bar magnet is 'permanent' Think of a scrap-yard. If the magnet they use to pick up huge quantities of metal were permanent, they'd have to manually remove every piece. With an electro-magnet, they simply turn the power on to pick up a load, and off when they want to release it. You can make your own electro-magnet with a battery, some wire and a large nail.
How is an electromagnet different a bar magnet?
a electromagnet is bigger than a bar magnet
When a electro magnet flows through a coil of wire wrapped around a bar of iron it makes what?
a magnetic field
Is a bar magnet magnetic?
A bar magnet is a magnet of rectangular shape with a north and and south end, which are sometimes coloured different colours to indicate which end is which.
What are the uses of electro magnet?
The most common uses of an electro magnet begin with the harnessing of electricity in windmills.
What does the electro magnet prove about electricity?
An electro magnet proves that Electricity and Magnetism always co-exist in nature
What magnet can be switched on and off?
An electro-magnet can be turned on and off.
Electro magnet used for?
A electro magnet is used for lifting things by the magnetic force provided by the amount of coils and the size of the battery
