What Are Magnets Used For?
Magnet has applications in various industries, from house use and medicine to the automotive and manufacturing industries. Here, we briefly discuss magnet uses in every industry for general understanding.
What Are Magnets Used For In Everyday Life
Magnet has a variety of use cases in everyday life. From your home to your offices, you might never know that magnets are available in how many unexpected places and playing unexpected jobs.
Household Appliances
Whether you know it or not, magnets are everywhere in your homes, playing hide and seek. Let's find some obvious places where they are performing important tasks, both practical and decorative.
Refrigerators:
Nowadays, most refrigerators contain magnetic seals, which help the doors to close tightly and preserve the fridge's energy and freshness of food. Most people think that the refrigerator door closes automatically because the fridge itself is pulling its door, but that's not the case. These doors have a weak magnet embedded in the seal which makes the door close automatically. Additionally, the most common household magnets are known as fridge magnets. These magnets serve the function of attaching pictures, holding notes, or lists on the fridge. Moreover, some people also use alphabet magnets for decoration purposes, like spelling out fun messages and names on the fridge.
Toys
You can even find magnets in the toys of children, like puzzle games or building sets that have magnets for fun and interactivity. Moreover, toy trains also have magnets added to attach the carriages.
Furniture and Household Appliances
Other places where magnets perform well are in household appliances and furniture. Although the examples are not too many, you will still see them in electric fans, microwaves, and motors, where they are essential for their operations. Moreover, magnets are also used in kitchen and bathroom cabinets, cupboards, and drawers to make their doors securely closed.
Jewelry
Your jewelry also contains magnets, which is quite shocking. During the making process, the manufacturers use magnetic clasps in the making of various items from bracelets and beads to necklaces and earrings. These magnetic clasps help in joining the two ends of the jewelry while wearing around the wrist and neck. Not only in jewelry, magnetic clasps are also part of bags, purses, and accessories, where they provide convenience and style. Moreover, there are brands that offer magnetic earrings for people with no pierced ears.
Cordless Tools:
Screwdrivers and drill machines also have magnets in their motor system to hold bits in place.
Door Locks:
Now, the doors are also equipped with magnetic locking systems that provide more security in residential and commercial spaces.
Magnetic Strips:
Another unexpected place where you can find magnets is on credit cards and IDs. The purpose of adding magnetic stripes on the back of IDs and debit/credit cards is that they store data securely for transaction purposes.
Magnetic Whiteboards:
Homes and offices often have whiteboards for learning and working purposes. Some of these whiteboards contain magnets for easy organization of their accessories, like attaching erasers, markers, and notes.
Industrial Use of Magnets
Magnets have a variety of industrial uses, like
Watchmaking
The biggest use of magnets is in watchmaking, where you can find their practical use in all types of watches like ball bearing watches, quartz watches, and mechanical watches.
● Ball bearing watches: There is a network of magnets in these watches that hold the balls in place while allowing ball bearings to move the balls precisely to show time.
● Quartz watches: Instead of a magnet network, quartz watches have coils in them, which produce a magnetic field. The watches use this magnetic field to drive their magnetic rotors.
● Mechanical watches: Magnets improve components like balance springs and magnetic escapements in mechanical watches. Advanced materials with magnetic properties ensure precision and durability by reducing friction and wear in the moving parts.
Automotive Industry
● Electric Motors & Sensors: Magnets power energy-efficient motion in hybrid and electric vehicles and help them provide optimal performance. It also helps vehicle systems in various functions like navigation, braking, and system reliability.
● Automobile manufacturing: High-strength permanent magnets, often composed of rare earth materials, are key in hybrid and electric vehicle production, enabling the conversion of mechanical force into electrical energy.
● Mag-Lev Trains: These trains hover above tracks by utilizing large magnets for levitation and achieve speeds of up to 200 mph through magnetic repulsion.
Use of Magnets in Computer Technology and Electronics
Magnets are helpful in storing data securely; here are some examples.
Hard Drives
Magnets in hard drives play a vital role in storing and retrieving data by altering the direction of magnetic material in specific segments, which represent information that computers can later read. Hard disk drives (HDDs) use three permanent magnets: one as an actuator for the read-write arm, one for reading-writing actions via the platter, and one in the spindle motor for platter rotation. While solid-state drives are gaining popularity, magnetic hard drives remain widely used for their efficiency.
Speakers and Headphones
Speakers and headphones use magnets to convert electrical signals into sound waves, delivering high-quality audio through vibrations amplified by diaphragms or cones. The interaction between magnets and electromagnetic coils produces vibrations, with the frequency determining the pitch and intensity of the sound. Found in devices like televisions, headphones, and smart speakers, these magnets are essential for transforming electronic signals into audible sounds.
Mobile Phones
Even in tablets and smartphones, Magnets are used to hold mobile covers in place and to align charging cables.
Magnets Use in Power and Industry
When it comes to industrial application, magnets serve many sectors efficiently, like
● Generators: Electric generators have magnets that are installed to convert mechanical energy into electrical energy, thus producing electricity.
● Motors: On the contrary, magnets perform the opposite function in motors, where they convert electrical energy into mechanical energy to power various devices.
● Wind Turbines: Magnets are important for generating renewable and sustainable energy like generating electricity through wind energy.
● Material Handling: Magnets are also helpful in material handling. Cranes have electromagnets that help construction workers efficiently lift heavy metal objects safely.
● Recycling: The use of Magnets is also beneficial in recycling centers, where they efficiently separate particular metals and help in the process of splitting up materials. Moreover, by using magnetic separators, you can also separate ferrous metals from all other waste.
● Mining: Magnets are also helpful in extraction processes as they are able to separate useful metallic ores from smashed rock.
● Food Processing: While food processing, the companies use magnets to remove small metal fragments from products like flour, grains, etc.
Magnets Use in Medicine
The use of magnets in medical sciences is quite interesting. Although it seems impossible, magnets are performing various functions in the medical field and change it completely with their unique properties:
