Permanent Magnets | Custom Magnets & Magnetic Assemblies

Permanent magnets are made from special alloys (ferromagnetic materials) such as iron, nickel and cobalt, several alloys of rare-earth metals and minerals such as lodestone. Unlike electromagnets, permanent magnets produce a persistent magnetic field without the need for any external source of magnetism or electrical power.

Magnetic Material - an overview | ScienceDirect Topics

2012-01-14· The primary criterion allowing for classification of magnetic materials is coercivity, which is a measure of stability of the remanent state. Soft magnetic materials are characterized by low values of coercivity (Hc <10 3 A m –1), while the coercivity of hard magnetic materials (usually permanent magnets) is higher than 10 4 A m –1.

Permanent Magnets Materials and Magnet Systems

The earth is a gigantic magnet, with a North Pole and South Pole. As a permanent magnet it is surrounded by a magnetic field. Since the North Pole of a magnet refers to the North, and because opposite magnets attract each other, teogra-he g phic North Poleis a magnetic South Pole. The geographic and magnetic poles are not at the same loca- tion.

10 Examples Of Permanent Magnets - ALB Materials Inc

The major difference between an electromagnet and permanent magnet is that the former can have a magnetic field when electric current flows through it and disappears when the flow of the current stops. On the other hand, permanent magnets are made up of magnetic material that is magnetized and has its own magnetic field.
