What is Degaussing and How Does it Work

When it comes to properly managing electronic waste, there are various ways that consumers can go about this. When determining which way to choose, you want to consider if it will allow for keeping your information safe. This is because simply deleting your information on the computer does not mean it’s erased. Information is stored on hard drives, and when a computer is retired, the old information can still be resurfaced. To combat this, taking your e-waste to an electronic recycler is a popular option. Another option is to degauss your hard drive. You may be wondering, what is degaussing? Read on to find out more!


Degaussing is a process that is used in order to make sure that information stored on hard drives cannot be recovered. The process involves putting the hard drive, or other form of media, into a powerful magnetic field. The magnetic field of the degausser is so powerful, the magnetic data that is on the hard disk or tape becomes neutralized, effectively erasing or making information unreadable. Since all forms of magnetic media have a magnetic property, the magnetic property can be interfered with. A degausser is able to erase information because it generates a magnetic field so powerful that it will permanently remove the magnetic properties that allows for the media to store information. If those magnetic properties are removed, then the recorded data becomes unreadable.


Degaussing is a popular option when it comes to getting rid of electronic waste. When you send e-waste to a landfill, it does not guarantee that the information that is stored there will remain safe. Additionally, e-waste in landfills causes harm to the environment and increased the pressure on our natural resources. Degaussing ensures that your information remains safe as all information that was once stored on your e-waste, becomes irretrievable.
