Most CD players use electromagnetic switches called relays. Have you ever turned on the power on your CD player or another appliance, and heard a click immediately before it went on? That's a relay doing its job. In a relay, a small current runs through a coil which is right next to a switch with a magnet in it. The coil pulls on the switch, closing it and turning on the device. Relays are useful because they use a small current to control a much larger one. As a result, they are often used in the power supplies of electronic devices such as CD Players

What does a magnet do to a paperclip?
A magnet can attract a paperclip by creating a magnetic field that pulls the iron-based metal of the paperclip towards it. This attraction is known as magnetic force, and it causes the paperclip to stick to the magnet.
What will happen to poles in a magnet when you cut a magnet in two?
Nothing happens, except that now you have two magnets. The poles of a magnet are not actually localized at the two ends of the magnet but are inherent to the magnetic properties of the magnet. As the magnetic properties are not altered by a modification of the magnet such as cutting it in half, there will be no effect on the poles of the magnet.
Is magnet used in Cd's and DVD's?

Can a magnet erase the memory of a CD or floppy disk?
The best way to clean a floppy disk is with an electromagnet not a regular magnet. If you can put it to the back of a large speaker when the speaker is turned on, that should work. On the other hand, if you wait about 10 years, that will also do it.
Is CD contain magnet?
No, CDs do not contain magnets. CDs use a technology that relies on the reflection and refraction of light to read and write data, and do not require any magnetic components.
How do you erase a mac book pro with out the CD?
Remove the hard drive and a powerful magnet on it. This works but can lead to slightly unpredictable results.
Can a CD be affected by a magnet?
No, unlike the platters of a hard disk drive, Compact Discs (CDs) are made from polycarbonate and recorded on by lasers, and thus are not susceptible to damage by magnets.
What data storage device will not have its data scrambled by a magnet?
Neither a DVD nor a CD would be affected by magnetic fields, because the information is digitally encoded using optical media.
What is Something that has two poles is describes as?
A magnet. It is described as a Magnet.
Why does a mineral magnet stick to a magnet?
a mineral magnet can stick to a magnet because a mineral magnet has to poles the north and the south poles
Making a magnet with another magnet?
if you have a magnet and a magnetic matereal, rub the magnet from one end of it to the other. do this several times and it will eventualy be a magnet.
Is magnet a forcewhy?
No, a magnet is a physical object. However, a magnet can EXERT a force.
