Magnets are used in the industrialized products and have an impactful influence on our daily lives. So what are some uses of these magnets?
The permanent magnets are used in cars, motors, speakers, sensors and much more. The common use of the magnet is the pulling force to attract magnetic items but it has varied functions in electronic tools as well.
So what is this permanent magnet all about? Let us know more about this magnet.
A permanent magnet is originally made of the ferromagnetic materials that have been magnetized. The reason why it is permanent is that it has a persistent magnetic force which attracts other magnetic objects. So a magnet which retains its properties in the absence of inducing field/current is the permanent magnet.
Permanent means lasting or the one intended to last or remain unchanged indefinitely. The next question arises that how are these magnets created and how they are different from electromagnets. Let us read below to understand the difference.
An electromagnet has the magnetic field which is produced along with an electric current. A simple electromagnet is made from a coil of wire which is often wrapped around a core of ferromagnetic materials like Iron. This means that the magnet has the properties only upon the application of the electric current. This magnetic force could be turned off and it is easier to manipulate the usage of this magnet by controlling the amount of electric current which is supplied to it.
Coming to the permanent magnets these are different than electronic ones and are a necessary part of modern life.
These are found in or used for producing almost every modern convenience beginning from speakers in the mobile phones, air conditioners and much more. These magnets are used in technological applications including Hall Effect sensors, thin-film coating equipment and much more. In all these applications the designed permanent magnet must have high strength, corrosion resistance and resistance to demagnetization because of the excessive heat. Manufacturers have gained experience in designing and producing these magnets for meeting the needs of industries with permanent magnets and magnetic assembly applications. There are varied permanent magnets available for designers beginning from ferrite to the rare earth materials. Designers have to analyze the field strength of the magnet and the magnetic output of the magnetic materials before deciding on the appropriate magnet. The permanent magnets of nowadays are 60 times as strong as they were 90 years ago.
