Have you ever used a degausser before?

No, I haven't. What does it do?

It's a device that removes unwanted magnetic fields from storage media.

That sounds interesting! I might need one for my old hard drives.

Root Explanation

**Degausser** → The word is formed from the prefix "de-" (meaning to remove or reverse) and "gauss" (named after the mathematician Carl Friedrich Gauss, who contributed to the understanding of magnetic fields). The term refers to a device that removes or reduces the magnetic field from an object, effectively reversing its magnetization.

Memory Tip

Think of 'removing' ('de-') the magnetic influence associated with 'Gauss' — that's why a degausser is a device that eliminates magnetic fields.
