Magnets play crucial roles in various industries and in the devices we use every day. From computers and electronics to health and medicine, magnets power our daily lives. We don’t always think of magnets as key components in making our households run smoothly, but the fact is, they do.
From vacuum cleaners to doorbells, washing machines and telephones—they all require magnets. So do credit cards, MRI machines and electric vehicles and computer data storage on hard drives. Magnets help alter the direction of the magnetic material on the hard disk to represent computer data. Additionally, magnets are present in small speakers, USB cables, radios, televisions, and other electronic gadgets we rely on daily.1
Magnets in electric generators turn mechanical energy into electricity, while some motors flip that, turning electricity back into motion. Electromagnets play a vital role in recycling by grabbing large metal pieces. Moreover, magnetic drums are used in mines to separate metallic ores from crushed rock. Food processing units also utilize magnets to remove small metal pieces from grains and other food items.2
There are three main types of magnets:
• Permanent magnets retain their magnetic properties. Examples of permanent magnets include neodymium, ferrite and alnico. Nikken products most often contain either neodymium or ferrite magnets. Although neodymium magnets are considered the strongest and most expensive, ferrite magnets offer the most corrosion resistance.
• Temporary magnets are made out of soft metals that become magnetic when close to a magnetic field or electrical current. Examples include common use items such as iron nails, paper clips and refrigerator magnets. These items lose their magnetism when they are removed from the magnetic field.
• Electromagnets are created by running an electrical current through a coil with a metal core. The energized coil creates a magnetic field. When the current is shut off, the magnetic field disappears.Electromagnets are used for applications that require strength, such as rail road tracks, motor engines, MRI machines and cranes.3
Magnets are indispensable and make our lives easier and more efficient. At Nikken, magnets are incorporated into many of our products. For example, neodymium magnets are incorporated in the Kenko Precision Set’s sphere and wand. Our Kenko mSteps® and Kenko mStrides® are insoles with patented DynaFlux® magnetic technology. Even our jewelry— necklaces, bracelets and earrings—incorporate magnets.
Have you seen how dogs turn around in circles before they find the perfect spot to relax in? They instinctively know how to access the natural magnetic energy in their changing environment. Humans are less in tune with planet Earth, but since contemporary lifestyles cannot function smoothly without magnets, learning about them and reaping the most benefits from them can make daily living so much more enjoyable!
