There are three main sorts of magnets, permanent magnets, temporary magnets, and electromagnets. Of those three types, Permanent magnets are those the typical person is most conversant in. An honest example of a standard, everyday static magnet maybe a fridge magnet.

Permanent magnets are considered permanent because once they're magnetized they keep their level of magnetism. A static magnet is an object made up of a cloth that's magnetized and it creates its own persistent magnetic flux.

Permanent magnets are often created in almost every possible shape. An honest static magnet should produce a high magnetic flux with a coffee mass. Additionally, once you are trying to find qualities of an honest static magnet you would like to make sure the magnet is stable against the influences which will demagnetize it.

There are varieties of various sorts of permanent magnets and every type has different characteristics and properties. What differentiates these permanent magnets includes:

· How easily they will be demagnetized

· How strong they're

· How their strength changes counting on the temperature

Types of permanent magnets include:

· Neodymium

· Samarium-cobalt

· Alnico

· Ceramic (also referred to as ferrite)

Neodymium and samarium-cobalt magnets are classified as rare-earth element magnets. Rare-earth element magnets are permanent magnets that produce the most important magnetic flux with the littlest mass. These magnets are the strongest of all the permanent magnets and are difficult to demagnetize.

Alnico's name springs from its components. Alnico is formed of aluminum, nickel, and cobalt. This sort of static magnet isn't easily suffering from a temperature, however, it's easily demagnetized.

Finally, Ceramic ferrite magnets are perhaps the foremost popular sort of magnet, mostly due to their flexibility. Ceramic magnets are flexible and sometimes thin, meaning that they will be bent and moved during a number of various ways, making them excellent choices for advertising and marketing purposes. Ceramic magnets are fairly strong and not easily demagnetized; however, their strength varies greatly consistent with the temperature.

The uses of permanent magnets vary greatly, including:

Mechanical applications believe the attractive and repelling force of the magnet. Such applications include:

· Magnetic separators, magnetic holding devices

· Magnetic torque drives

· Magnetic bearing devices

Electrical energy applications believe using the magnetic flux of a magnet to convert energy into electric energy. Such applications include:

· Generators and alternators

· Eddy current brakes

Mechanical energy applications believe using the magnetic flux of a magnet to convert electricity to energy. Such applications include:

· Meters

· Motors

· Speakers

· Relays

Applications that are meant to direct, shape and control electron and ion beams do so employing a magnet's magnetic flux. Such applications include:

· Ion Pumps

· Cyclotrons

· Cathode-ray tubes

Permanent magnets are the foremost commonly known magnet and are utilized in the spread of products and environments. When choosing a static magnet you would like to think about its strength, performance in temperature and whether it's easily demagnetized.
