Applications of Magnets
Magnets are used in many and different ways at different situations and for different purposes. They have different sizes and can range from very small to very large giant like structures computers we use in our day to day lives contain magnets. Magnetic elements are present on hard disks and facilitate the extraction of computer data which is ‘read‘ by the computer code. Magnets are also found inside Televisions, radios, and speakers.
The small coil of wire and a magnet inside a speaker changes the electronic signal to sound vibrations. Generators also use magnets to transform mechanical energy into electrical energy. And they are always present where there are other types of mechanical or electrical motors which use magnets to change electrical energy to mechanical energy.
These magnets can also help cranes to move large metal pieces which cannot be lifted by humans. Magnets are being used in the separation and filtering processes of metallic ores from crushed rocks. They are also used in food processing industries to separate small metallic pieces from grains. There are various applications of these magnets only to mention the few above.
Drawbacks of Magnets
These are some major drawbacks of the magnets above. Molds and the sintered afterward make ferrite magnets. Therefore, they are very difficult to machine, so as a result, most ferrite products have very simple shapes and huge dimensional tolerances. The Samarium Cobalt magnet is very brittle, making it difficult to process small-sized products. Most magnets become denatured at very high temperatures and this is a major drawback of magnets. In addition, neodymium magnets are easily corroded and therefore need to be painted.
Conclusion
Magnets come in different forms, from simple bar magnets to very large permanent industrial magnets. Every type of magnet has two poles and even if they are cut in half, they will still have these two poles. Magnets are of great importance to the human community, but however they can be demagnetized at excessive temperatures and pressure.
