Magnets

It’s not uncommon for magnets to lose their strength. Known as demagnetization, it occurs with all permanent magnets. When a permanent magnet becomes demagnetized, it will produce a weaker magnetic field, resulting in a lower Tesla (T) reading. What causes … Read More

Not all magnets are the same. While they all produce an invisible field that attracts and repels other magnets — depending on the orientation of the poles — they are available in different types. Permanent magnets, for instance, are characterized … Read More

Magnetic catches have become a popular alternative to traditional latches. These small yet powerful devices are used in a variety of applications, from household furniture to industrial equipment. Consisting of two magnetic components, they are used to hold doors, cabinets, … Read More

It’s a common misconception that all permanent magnets are either ceramic (ferrite) or rare-earth. While ceramic and rare-earth magnets are certainly common, alnico is a popular alternative. An acronym for aluminum, nickel and cobalt, alnico magnets are used in musical … Read More

Magnets are used in a wide range of consumer and commercial applications. They are an essential component in speakers, microphones, motors, power generators, magnetic resonance imaging (MRI) machines, data storage devices and more. While all magnets produce a magnetic field, … Read More

Magnets come in a variety of styles. While some of these styles are used in consumer electronics, others are used in commercial applications. Cylindric retaining magnets, for instance, are commonly used in the manufacturing and construction industries. They are made … Read More

If you regularly lift and move heavy objects at work, you may want to invest in a lifting magnet. These rare-earth magnets are designed specifically for lifting. They typically have a neodymium base — neodymium is the strongest type of … Read More
