Permanent Magnet Materials

Magnet possesses the property of attracting or repelling other magnets. Special alloys like ferromagnetic material combined to form permanent magnet material. Ferromagnetic material is iron, nickel and cobalt, rare earth metals and minerals such as lodestone. This article has brief information about permanent magnet material, its formation process, its usage in our daily lives, its comparison with temporary magnets, its types, and applications. This article also tells us about its long lasting property.

What is the best type of permanent magnet materials?

Neodymium magnets consist of highest magnetic properties and they are rare earth magnet material. Consists of neodymium, iron and boron, these are the best type of magnet material available easily all over the world.


Following are the examples of permanent magnet.

1) Alnico (an alloy of aluminum, nickel and cobalt)

2) Ferrites (ceramic like material made from a mix of iron oxides with nickel strontium and cobalt)

How does permanent magnets formed?

Mainly permanent magnets are made by giving heat to the ferromagnetic material to the certain level. Effect of temperature and heating the metal is aligning and fixing the position of permanent magnets.

Usage of permanent magnet materials:

Permanent magnets can be used in computers, motors, cars, generators, headphones, speakers, sensors, magnetic strips and fridge magnets. Permanent magnets are also used in hard disc, televisions, and transducers. Commonly use of permanent magnet is force of pulling for the attraction of other magnetic items. It is also used in magnetic knife strip holder, lawnmower and electric toothbrush.

Everyday items having permanent magnets:

Following are the items we used in our everyday life containing permanent magnet.

  1. A) Fridge magnets
  2. B) Magnetic cabinet latches
  3. C) Audio speakers
  4. D) Electric motors
  5. E) Electronic devices
  6. F) The internet

Temporary magnets Vs permanent magnets:

External source of magnetism or power supply is not needed for the magnetic field of permanent magnet. While temporary magnets only start working when external source of magnetism or power supply is attached to the magnet.

Long lasting property:

Permanent magnet has long lasting nature. It cannot lose its magnetic strength over years. Only through heating it can change its nature and loses its magnetic strength.

Properties of magnets:

There are three very well-known properties of magnets.

1) All of them attract precise or certain metals towards themselves

2) They are having north poles and south poles.

3) Opposite poles are attracted to each other while same poles will repel each other.

Seven types of magnets:

Here is the list of magnets given below having magnetic properties.

1) Neodymium iron boron NdFeb

2) Samarium cobalt SmCo

3) Alnico

4) Ceramic or ferrite magnets

5) Temporary magnets

6) Electromagnets

7) Superconductors

Applications of permanent magnets:

Permanent magnets are the very unique, versatile and beneficial tool present around us. It has the property to attract metal to itself and vice versa. It posses properties like coolness, strongest of all. It can produce electricity, magnetic fields, Flux and much more. It has the ability to change mechanical energy to movement or motion.

Uses of permanent magnets:

Permanent magnets are beneficial and useful in several ways. It can be used commercially, in house, in clothing etc. Here are some examples given below:

1) Refrigerator magnets

2) Pain relief magnets

3) Name tag magnets

4) Button or snap changing

5) Key chain magnet

6) Dart boards

7) Wrecking cranes in scrap yards.

8) Compasses

9) In all forms of media.

How much current can one magnet produce?

Magnet can produce or generate voltages from 69.5 to 223.7 V and frequencies range from 33.5 to 50.9V at rotational speeds of 2000 t0 3000rpm.

 Items used in permanent magnets:

According to the Materials used in permanent magnets, these items can be present in the permanent magnets.

1) NdFeB magnets

2) SmCo magnets

3) Ferrites magnets

4) Alnico magnets

5) Rubber magnets

6) Motor magnets

Permanent Magnet materials are basically formed by ferromagnetic materials which generate magnetic fields and don’t require any outer energy. Approximately 33.5 to 50.9V frequency are produced. They are able to produce variety of electrical, magnetical and flux, other than that it has ability to convert mechanical energy into motion. It also has ability to operate in high temperature. Mag spring has official website in which different types of magnets are available. Among them some of these have ability to demagnetize the magnets after cooling it.
