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.

Where are the two types of electromagnet and a bar magnet commonly used?
I'm not sure where a bar magnet is used, but an electromagnet is used in junkyards, and in some laboratories.
What kind of magnet is used in the hotel room door?
Electro Magnetic is correct
What is an example of a sentence using the word electromagnet?
Electromagnets are widely used now. Instead of traditional magnets.
What device can be used to determine the direction of the magnetic field in the electromagnet?
A compass can be used to determine the direction of the magnetic field in an electromagnet. The needle of the compass will align along the direction of the magnetic field lines produced by the electromagnet.
How is an electromagnet used in a radio?

What is the strength of an electromagnet proportional to?
The strength of an electromagnet is proportional to the number of turns in the coil, the amount of current flowing through the coil, and the magnetic permeability of the core material used in the electromagnet. Increasing any of these factors will increase the strength of the electromagnet.
Is electromagnet used in iron box?
Yes, an electromagnet is commonly used in an iron box. The electromagnet generates heat when electricity passes through it, which then heats up the metal plate at the bottom of the iron box to iron clothes.
What type of magnets are used in a electric bell?
electromagnet
How can you make an electromagnet rotate?
To make an electromagnet rotate, you can place it in the proximity of a permanent magnet. When a current flows through the electromagnet, it interacts with the magnetic field of the permanent magnet, causing the electromagnet to rotate. This setup can be used in devices like electric motors and generators.
How can the electromagnet be used to raise the barrier?
An electromagnet can be used to raise a barrier by creating a magnetic field when current flows through it. The magnetic field attracts the metal barrier, causing it to rise. By controlling the flow of current to the electromagnet, the barrier can be raised and lowered as needed.
