Curious people can’t help but get attracted to magnets. They’re pieces of iron that can somehow pull other metals to it. Ever since they were found in a naturally-occurring mineral called Magnetite, magnets have been used in household and commercial settings for many years now. Here’s a closer look at the uses of magnets:
1. Mag-Drive Centrifugal Pump
A magnetic drive centrifugal pump is used in industries that deal with corrosive liquids. Normal pumps won’t work on these liquids, as their metal parts would be corroded once the liquid touches them. Mag-drive pumps don’t need metal parts because they use a different type of suction. This makes them less prone to corrosion and leakage of harmful chemicals, making them a safer choice for humans, animals, and the environment.
2. Freezer Doors
Refrigerators and freezers have doors with tight grips. This is designed to keep out air and preserve the meat or food inside. These tightly-closing doors are made with the use of magnets.
3. Stereo Speakers
Speakers from stereos, television sets, and headphones have magnets installed inside them. The magnets amplify the audio that courses through these devices, allowing the hearer to understand the sounds more effectively.
A magnetic resonance scan (MRI) is a procedure used by doctors to diagnose human bodies if they have sicknesses. It works like an X-ray, in which a computer, a magnetic field, and a radio frequency pulse are used to produce images of a human body. Confusing as this may sound, the images produced are clear, with internal organs and bones shown.
Believe it or not, magnets are used in computers. They’re put inside not to attract other metals, but to store data made while using the computer. This includes your video game save files, pictures, videos, songs, and such.
Magnets have other uses besides being used to pin slips of papers on fridges. Magnets are used in industrial pumps, so they won’t get corroded by chemicals, in freezer doors, so they’ll close tightly, or in speakers so, they’ll get to produce sound. Without magnets, industries and individuals wouldn’t be as modernised as they are today.
