What else can I help you with?
What is an example of a situation where it would be best to use certain types of magnets to attract different types of objects?
Electro magnets can be used to attract metals temperarily while permanent magnet would be used for compasses.
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
What c is the piece of iron inside an electro magnet?
Core
How are electro magnets different from other magnets?
Electromagnets use electricity to create a magnetic field, which can be turned on and off. They are typically stronger than permanent magnets. In contrast, permanent magnets, like those made of iron or nickel, are always magnetic without the need for an external power source.
Is not a permanent magnet?
An electromagnet is a magnet while an electric current is running through the coil. Turn off the current and it is no longer magnetised, and is, therefore, not a permanent magnet.
What is the strongest type of permanent magnet?
An electro-magnet would be the strongest magnet. Or the sun itself would be the strongest natural magnet.
When all of the magnetic domains line up on their own what is the materia called?
electro magnetic feilds
What is an example of a situation where it would be best to use certain types of magnets to attract different types of objects?
Electro magnets can be used to attract metals temperarily while permanent magnet would be used for compasses.
What does the electro magnet prove about electricity?
An electro magnet proves that Electricity and Magnetism always co-exist in nature
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.
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
What are the release dates for The Wonderful Electro-Magnet - 1909?
The Wonderful Electro-Magnet - 1909 was released on: USA: 30 November 1909
What is produced whencoiled wire is spun around a magnet?
An electro magnet!
What is a magnet that is creadted from electric current through a wire?
Electro-Magnet
Is the magnet in a compass a permanent magnet or electronic?
A. Compasses typically use a permanent magnet.
