What is a ferit magnet?

ferrite magnets are a large class of magnets that include chemical compounds such as hematite (Fe _{2 ) and magnetit (Fe 3 4 ), the most naturally occurring magnetic mineral. They are ceramics and magnets, which means that they attract other ferromagnetic materials and attract or repel other magnets. The ferrite magnet is the simplest type of magnet, unlike more sophisticated magnets such as Alnico magnets or non -dense magnets (rare country magnets). They are also permanent magnets, unlike electromagnets that are only magnetic when they are supplied by electric current. Children often get toys consisting of iron administrations that can be moved with this type of magnet - usually magnetite. If the magnet is placed on the administration, the resulting formula that is drawn will reveal the shape of the magnetic spray. The Earth itself produces a similar magnetic field, although trillions more and about 10,000 times weaker. These kateGorization does not apply to the real hardness of the magnets - both types are fragile ceramics - but rather their coercive force. Depending on whether the magnet is soft or hard, it may have different applications. For example, a hard magnet can be used on a radio or hard disk, while soft can be used as a transformer core or solenoid core.}

The power of the ferritor magnet, like any other magnet, can be measured in Teslas. One Tesla represents one weber per square meter, while Weber is a unit of magnetic flow of drought that it would produce one volt of electricity if it would be reduced to zero in one second. Here are some examples, starting with weaker magnetic fields and the transition to stronger:

• Paramagnetic materials such as aluminum or oxygen have a magnetic field of about 300 nanotes.
• Earth's magnetic field has a power of about 31 microtes.
• The power of the typical magnet of the refrigerator is about5 milites.
• Bar Magnet is about 35 Milllitles.
• LoudSpeaker Magnet has a power of about 1 t to 2.4 tesla.
• The power of the strongest continuous magnetic field, which is still produced in the laboratory, is 45 Teslas.
