Basic Information On Earth Magnets

It might not be known to most people but technological devices in today’s age are powered by magnets. Quite a number of magnets are used in generators and computers. They are called earth magnets. The basic principles like other alloy magnets or regular iron apply in that they possess magnetic fields in the north and south poles. These work like regular magnets attracting unlike poles and repelling like poles. The strength of attraction is what sets apart earth magnets from its counterparts.


They are constructed from ferromagnetic metals or metals that can be permanently magnetized. This creates a very powerful magnetic pull. The downside is that they are brittle and can be shattered if thrown or dropped. The strength of the magnet is very strong. In certain cases, you hear of children swallowing these small magnets resulting in injury or death due to the magnets pinching a digestive tract organ. Larger earth magnets have been known to crush fingers if placed in-between them. Injury can be avoided if used carefully.





Developed in the late 1900s, earth magnets are utilized for wide range of tasks. One of the most common types available are neodymium magnets which are now more affordable and readily available to the public instead of only being restricted to the scientific community. These are very small magnets and the magnetic field range does not reach very far but it is powerful enough if you set two attracting magnets together which can cause breakage.

These magnets are frequently utilized in devices that run on electromagnetism, either partially or fully. This is the concept of magnetic force powering electricity. One of the examples of a common device that uses earth magnets today is the computer. The hard drive is powered by a magnet although it is well known that exposure to magnets will render a hard drive useless. Neodymium magnets are used in other things such as self-powered flashlights, cordless tools, refrigerator magnets and metal detectors just to name a few. For some people, they believe that magnets due to its pull possess healing properties. This however, has not been scientifically proven. In magnetic therapy, small earth magnets are used as a purifying method for water conditioning.


Currently, earth magnets are considered a stronger alternative as compared to other magnet types. Keep them away from small children. Avoid utilizing them in close proximity of a computer or any electronic device of the same nature as this might cause permanent damage. Information on debit or credit cards can be erased and as such, do not keep magnets in pockets or purses. By being aware and careful, mishaps can be avoided and you will find that these small magnets pose little danger as satisfaction can be attested by the large number of people that use them.
