Viral Sharing Information of Laptops & Magnetic Dangers

Since the early days of floppy disks, magnetic interference has been feared for the possibility of erasing data. In fact, a simple store-bought magnet can completely wipe out a floppy disk with ease. This fear has transferred into modern technology such as your laptop. Considering that many laptop accessories have magnets built into them, magnets pose less of a threat to your laptop than ever before.


Degaussing is the process of reducing a residual magnetic field. Older monitors that are prone to screen flicker problems, such as cathode-ray tubes (CRTs), require degaussing to assist in screen and resolution quality. Most modern laptops have either light-emitted diode (LED) or liquid crystal display (LCD) monitors, which do not require the degaussing process simply because they are non-magnetically controlled devices. Therefore, degaussing poses no threat to the modern laptop or monitor.

Magnetic Exposure

While some electronics can be adversely affected by magnetic interference, the likelihood of a laptop becoming problematic due to magnets is very slim. In order to produce magnetic interference in a laptop, the device would have to be in contact with a very heavy magnetic field. According to PCWorld, the only magnets powerful enough to wipe data off of a hard drive are laboratory degaussers and those used by government agencies.

Solid State Drives

Solid State Drives, or SSDs, are data storage devices that use an integrated circuit assembly to store information. As opposed to electro-mechanical devices such as hard disk drives and floppy disks, SSDs electronically store data. Solid state drives employ no moving mechanical parts, which is what makes them less susceptible to physical shock. SSDs are also relatively silent and resistant to magnetic fields, which make them an ideal solution for providing more reliable data storage on a laptop.

Magnetic Use

Several laptop accessories include magnets in the design of their products. For example, the NZXT Cryo E40 is a laptop cooling device that uses magnets in order to position the cooling fan in multiple positions and locations. Since the cooling fan is not set in a fixed location, it can be moved to the exact location producing the most heat. Several companies now utilize the power of magnetic energy to provide laptop users with accessories. These products include, but are not limited to, laptop stands, cases and cooling desks.
