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.
An electromagnet is not used in a compass as it needs electricity (an electric current)
no...only magnetic materials can be used as electromagnet...zinc is not a magnetic material
An electromagnet is used in an electrical engine, but an electrical engine contains normal magnets too.
the telegraph when typed when through electromagnet circuit's to get to the other person
I'm not sure where a bar magnet is used, but an electromagnet is used in junkyards, and in some laboratories.
An electromagnet is used.;)
Electromagnets are widely used now. Instead of traditional magnets.
Soft iron is used as the core of an electromagnet. It increases the strength of the magnet.
An electromagnet would be used to separate ferrous metals from other debris and it would also be used to lift loads of ferrous metals.
An electromagnet can attract the metal, leaving the plastic behind.An electromagnet can attract the metal, leaving the plastic behind.An electromagnet can attract the metal, leaving the plastic behind.An electromagnet can attract the metal, leaving the plastic behind.
to produce sound
if the electromagnet is strong the compass will point to it not north but if it is weak it will still point north
When you need a magnet you can turn on and off an electromagnet is used.
The electromagnet is part of the speaker, it causes the vibrations that become sound. Without the electromagnet, there would be no sound.

Iron is used for electromagnets.
Everywhere. Every electric motor is an example of an electromagnet. They are used for picking up scrap metal. Almost everything modern with moving parts has an electromagnet in it.
There are many uses of the electromagnet, it is used to invent generators and electric motors, used it to control the switch relay, use in practical industries, and even in an electric bell etc. Because the electromagnet is a type of magnet in which the magnetic field is produced by the electric current.
The electromagnet has two important advantages:* Electromagnets are much stronger than permanent magnets * They can be turned on and off
