What else can I help you with?
Magnetic disks use magnetic particles to store items such as data instructions and information on a disk's surface True or false?
true
What uses magnetic particles to store items on a disks surface?
Magnetic Disks, otherwise known as 'Floppy disks'. The last generation of these disks were 3 1/2" and used a ridgid plastic case, to contain the magnetic disk within. Not very floppy. The early versions were 7" and 5" and were contained in soft plastic outer sleeves. These were actually floppy.
Data is written to and read from a floppy disk via a magnetic?
Yes, data is written to and read from a floppy disk using a magnetic read/write head that interacts with the magnetic coating on the disk. When writing data, the magnetic head aligns the magnetic particles on the disk surface to represent the information. When reading data, the head detects the magnetic orientation of the particles to retrieve the stored information.
Where does hard disk information stored?
In magnetic particles on the hard drive disk surface. The drive head reads the magnetic particles and interprets if they are ones or zeros. The head doesn't touch the disk surface but resides about .00005 thousands away from the surface. Just opening the drive housing in an unclean environment can render the drive unusable. It also voids the warranty
How prominence like sunspot?
Solar prominences are gouts of charged particles carried from the surface of the sun into space. These particles are carried by magnetic fields, but of course the surface of the Sun is too hot for any magnetic material (>6 000oC). The source of the magnetic field in turn is caused by huge electrical currents of charged particles near the Sun's surface.
What prevents particles from the sun from reaching the surface?
Charged particles from the Sun will not reach the surface of the Earth because they are mostly deflected around it by the Earth's magnetic field (the magnetosphere), but where the particles are deflected towards the surface near the Earth's magnetic poles, they interact with the gas high in the atmosphere to form the Auroras and do not penetrate through to the surface.

What is the device that reads and records information on disks?
Head – The device that reads and writes the information—magnetic or optical—on the disk surface.
What is magnetic particle testing in NDT?
This ndt method is used for the detection of surface an near to surface discontinuities in ferromagnetic materials,by applying a magnetic field and a medium sensitive to areas of magnetic flux leakage.This medium will be attracted,and held,to the part surface(by the flux leakage)and the visual indication of a discontinuity then interpreted by a qualified operator.
Prevents charged particles from the sun from reaching the surface?
The Earth's magnetosphere acts as a protective shield, deflecting solar wind and charged particles from the sun. This helps to prevent these particles from directly reaching the surface and causing potential harm to living organisms and sensitive electronic systems on Earth.
