There are three main forms of magnets – permanent, temporary and electromagnets. Of these three types, permanent magnets are the type an average person is most familiar with. Among a typical, everyday magnet is usually a fridge magnet.
They can be considered permanent because if they are magnetized they maintain their degree of magnetism. It is really an object produced from a cloth that is certainly magnetized also it creates its very own persistent magnetic field.
They could be made in nearly every possible shape. A superb magnet should make a high magnetic field with a low mass. Additionally, while you are seeking qualities of a good permanent magnet you want to make sure that it’s stable from the influences that can demagnetize it.
There are a selection of different forms of these and every type has different characteristics and properties. What differentiates these includes:
• How easily they might be demagnetized
• How strong they’re
• How potency and efficacy changes with regards to the temperature
Kinds of permanent magnets include:
• Neodymium
• Samarium-cobalt
• Alnico
• Ceramic (also called ferrite)
Neodymium and samarium-cobalt are classified as rare earth magnets. Rare earth magnets make the largest magnetic flux with all the smallest mass. These are famous for is the strongest of all permanent magnets and they are challenging to demagnetize.
Alnico’s name comes from its components. Alnico consists of aluminum, nickel and cobalt. This type is just not easily troubled by temperature, but it’s easily demagnetized.
Finally, ceramic or ferrite magnets might be the most used type, ultimately because of their flexibility. These are flexible and quite often thin, which means that they can be bent and moved in many other ways, driving them to excellent selections for advertising and marketing purposes. They’re fairly strong and not easily demagnetized, nevertheless strength differs in accordance with the temperature.
The uses of permanent magnets vary greatly, including:
1. Mechanical applications make use of the attractive and repelling force of the magnet. Such applications include:
• Magnetic separators & holding devices
• Torque drives
• Bearing devices
2. Electric power applications depend upon while using magnetic field to convert mechanical energy into electric power. Such applications include:
• Generators and alternators
• Eddy current brakes
3. Mechanical energy applications count on while using the magnetic field to change energy to mechanical energy. Such applications include:
• Meters
• Motors
• Speakers
• Relays
4. Applications that are supposed to direct, shape and control electron and ion beams. Such applications include:
• Ion Pumps
• Cyclotrons
• Cathode-ray tubes
Permanent magnets would be the common and so are found in various products and environments. When selecting these you intend to consider its strength, performance in temperature and be it easily demagnetized.
