Magnets and Their Uses in Various Industries
Magnets, just like computers, have proven over the years to be highly versatile tools and are used in a variety of sectors and industries for a variety of uses. Below are some of those industries and their uses.
Industries that Use Magnets and What They Use Them For
1. Mining Industry
Since the mining process usually produces essentially as many impurities as it does metals in extracted metallic ores, it is important to separate the actual metals from these impurities. Since most metals are magnetic and non-metals are not, magnets are a cost-efficient and easy way to separate these precious metals from the unwanted impurities. They are also used to collect the fine particles of metals that have been scattered during the blasting process by separating them from the non-metallic debris and dust.
2. Food and Pharmaceutical Industries
3. Tech Industry
4. Financial Industry
The financial industry is yet another industry where magnets have been utilized to brilliant effect. This application of magnets comes in the form of debit and credit cards. These cards function as a form of magnetic storage ─ information is stored on them magnetically and can then be read at a later date by the appropriate readers. In fact, these cards work essentially in the same way hard drives, diskettes, and tapes work.
Magnets in the transport industry are also employed for various uses. First, they are used for sweeping roads and airport runways of scrap metals, which could cause damage to vehicle tires. They are also the basis for maglev (magnetic levitation) transportation, a method of (train) transportation that uses two sets of magnets, one for repelling the train and making it hover over the tracks and the other for moving the hovering train at great speeds.
6. Electric Power Industry
Magnets are also used in the production of electricity. They are an important component in the conversion of mechanical energy to electricity in so many generators.
7. Security Sector
Magnets, or at the very least the principle of magnetism, are utilized in the security sector for the creation of metal detectors. While metal detectors don't basically contain magnets, they utilize electricity flowing through transmitter coils to create a magnetic field. This practically makes them temporary magnets. This magnetic field is what detects metals.
8. Medicine and Research
Magnets also find uses in the field of research. Being a vital part of medical equipment like the MRI (Magnetic Resonance Imagin) machine as well as research equipment like particle accelerators.
Impressive right? And those are not even all either. Magnets have been used for so much more want to find out more and are even finding newer applications from time to time! Want to find out more about how magnets are used? Why not check out our other blogs on magnets, how they work, and their uses.
