Sharing our love for magnets.
Magnets have been discovered in ancient times and were documented over 2500 years ago in Greece, India, and China. The word magnet in Greek meant "stone from Magnesia", a part of ancient Greece where lodestones were found. Ancient Chinese people found that if a lodestone was suspended so it could turn freely, it would always point in the same direction (toward the magnetic poles).
Magnets have emerged as important components in many industrial fields, crucial for our daily life.
Magnets are responsible for viewing images on the TV and computer screens. Tiny magnetic fields placed in patterns are providing the storage ability of CDs and video tapes. Magnetic sweepers are used in industries to help reduce maintenance costs and eliminate flat tires at airports, loading docks and work sites. Credit cards and ATM cards have a magnetic strip that encodes the information needed to contact an individual's financial institution and connect with their accounts. Magnets are used to separate between materials and sort between magnetic to non-magnetic materials.
In recent years we find magnets to drive fast long distance trains - Maglev transport is a means of flying a vehicle or object along a guideway by using magnets to create both lift and thrust, only a few inches above the guideway surface. Maglev trains can travel very fast, up to 480 km/h (300 mph). Maglev trains were launched in Japan in 1997. Shanghai Maglev Train is the first commercially operated high-speed magnetic levitation line in the world. Hospitals use magnetic resonance imaging to trace symptoms in a patient's organs without invasive surgery.
Magnets are found in every day home devices as speakers, microphones, microwaves, toys, cell phones, screens and more. Evident by Apple's recent patent applications, many of the future mobile devices will rely on magnets and provide new intelligent solutions.
While we experiment with new technologies enabled by magnets, we dedicate this space to recent innovations related to magnets. We invite you to share your magnetic obsession with us.
