Magnetism is used to operate the fan motors and the disk drive motors as well as operating the "voice coil" that causes the disk read/write heads to move. The surfaces of the hard disk "media" is magnetized to represent data. The hard disk read/write heads are nothing more than small electromagnets and as the heads move across the spinning disk media, magnetic data is sent or received by the disk heads.
Older computers used a magnetic "core" to store data. That's the origin of the term, "core memory". With the decrease in cost ind incredible speed of transistor based memory, nobody uses magnetic core any more.
What else can I help you with?
Father of magnetism?
Gilbert
Which scientist discovered the relationship between electricity and magnetism?
The relationship between electricity and magnetism was discovered by the scientist Michael Faraday in the 19th century.
How ASCII is used in the computer?
ASCII is a form of character encoding, so it can be used by your computer for any task.
What is interactive computers?
computer you can do things on... you used one to ask this question computer you can do things on... you used one to ask this question
Set of computer programs used on a computer to help perform tasks?
software
Are there electricity and magnetism in a computer?
Yes
How is there electricity and magnetism in a computer?
It is plugged into a wall outlet.
Can magnetism field work?
magnetism works by the type of metal used to pull other type metal to it.
What are the magical properties that people used to attach to lodestones?
Magnetism, people believed it was magical because they had no understanding of the forces of magnetism.
What is name commonly used for moving charge?

Which of these is not a way by which objects can become charge?
magnetism magnetism magnetism
Is friction used for a nail to pick up paperclips?
no it is magnetism
What is an example of electricity and magnetism being used?
An electro-magnet.
What is permanent magnetism?
Permanent magnetism is magnetism that is permanent. I think...
What is difference between residual magnetism and retentivity?
Residual magnetism and remanence are the same thing. The term residual magnetism is often used in engineering applications. Both terms describe the magnetization, and measure of that magnetism, left behind in a ferromagnetic material after the external magnetic field is removed.
Can you produce electricity even without magnetism?
yes we can produce electricity without magnetism by using semiconductor for example photo diode is used in solar cells.
What magnet keeps its magnetism for a long time?
Neodymium magnets are known for retaining their magnetism for a long time due to their strong magnetic properties. They are commonly used in various applications where long-term magnetism is important, such as in electric motors and generators.
