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.
Practical uses for an electromagnet are - Moving metal in scrap heaps, Removing objects from peoples eyes,opening locke, sliding bolts, switching switches in cat scans and in computers.
Two uses of an electromagnet:
1. To magnetize your dirty penis.
