Why are magnets used?
Electro magnets can be very useful to carry heavy loads of iron and metal from one side of a factory to another. Electro-magnets are formed by shooting electricity through a coil of copper.
What are electro magnets used in?
car wreck (scrapyards) metel dedectors at airports
Which magnets can retain their property for a short period of time?
Electro-magnets
Do magnets repel non magnetic materials not including electro-magnets?
of course not.
How are solendoids related to electro magnets?
duplicate
Are bar magnets stronger than electro magnets?
Yes, because electromagnets can lose their magnetism.
Are electro magnets sometimes called artificial magnets?
Yes, electromagnets itself is an artificial magnet.
How are electromagnets used to make electric power?
Electromagnets are used to make electric power because magnets are a type of electricity,and electro is at the front.
What can a electromagnet be used for?
If your computer is using a CRT (instead of an LCD or plasma screen), the electromagnet is causing the electron beam to "bend" as it passes across the screen to make the image. If your computer uses a hard-drive, electro-magnets are used to position the read/write head, to spin the disk and to write to the head. An electro magnet is also used to spin the motor of the cooling fan(s). Electro-magnets are part of your automobile's electrical system as well. The starter motor uses electro-magnets as do all electric motors, the ignition coil is little more than specialized electro-magnets, the automatic door actuators are electro-magnets as are the injectors and any relays. Electro-magnets are everywhere, you just need to know where to look.
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.
Where are electromagnets used in industry?
An electromagnet is used in an electrical engine, but an electrical engine contains normal magnets too.
How are magnets used in making a car run?
magnets are used in the starter and the alternator. in the starter, electro magnets are used to run the electric starter motor and also to bring the pinion gear into the flywheel. in the alternator magnetic current is used to generate electricity to charge the battery. there may be some small magnets in the transmission to pick up metal fillings.
