Electromagnets are soft iron cores that are made into magnets on passing anelectric current through the coil surrounding them. A permanent magnet is something that is an innate ability of a magnet that continues to show magnetism even if it is removed from themagnetic field. So, here if we differentiate between an electromagnet and a permanent magnet, it seems that permanent magnets are better than electromagnets; however, each of these has its own advantages. This article discusses the difference between an electromagnet and a permanent magnet in points. Electromagnetism MeaningThe word ‘Electro’ inelectromagnetism talks about the magnetism that is caused by the effect ofelectricity, and soon it loses its magnetism when it is brought away from the area of the magnetic field. Permanent Magnetism MeaningThe word permanent talks about something that remains firm or permanent. Here, permanent magnetism means a magnet that retains its magnetism after the removal of the magnetizing force or after taking a magnet from the vicinity of the magnetic field. The below diagram represents the difference between the electromagnet and permanent magnet: (ImagewillbeUploadedSoon)
Distinguish Between the Electromagnet and Permanent Magnet:
Now, let’s discuss more to differentiate between the electromagnet and permanent magnet: The table below lists the difference between the electromagnet and permanent magnet Difference between Permanent and Electromagnet
Uses and Advantages of using Permanent MagnetThe permanent magnets are particularly efficient at attracting other magnetic objects and a lot of modern appliances need to convert the mechanical motion into a kind of force or energy to work. One of such appliances is inductions and generators. They convert the motion into energy with the help of permanent magnets. They are also used in televisions, speakers, or headphones as they need to create a magnetic field around them to work. Permanent magnets are also not so expensive and that is why the usages of permanent magnets in the industrial sectors prove to be quite a good idea. They are portable and consume less space. The best part of permanent magnets is that they do not need a separate wiring system in order to create the magnetic field and that is why their manufacturing cost is also quite low compared to the electromagnets. The appliances that incorporate permanent magnets into their system can be used in various ways and multiple times and that is why they are quite cost-effective. Since permanent magnets do not need any external power supply or force to create the magnetic field, variation in the power of the magnetic field in different areas cannot be seen. Using permanent magnets can provide you with a uniform magnetic field. |
