  • Magnetic force on a wire

What is magnetic force?

What is the magnetic force? The magnetic force is a consequence of the electromagnetic force, one of the four fundamental forces of nature, and is caused by the motion of charges. Two objects containing charge with the same direction of motion have a magnetic attraction force between them. Similarly, objects with charge moving in opposite [...]

Magnet Materials

Permanent Magnet Materials Permanent magnet lodestones contain magnetite, a hard, crystalline iron ferrite mineral that derives its magnetism from the effect the earth's magnetic field has on it. Various steel alloys can also be magnetized. The first big step in developing more effective permanent magnet materials came in the 1930s with the development of Alnico [...]

  • Magnet Background of permanent magnets

Magnet Background

Magnet Background A magnet is a material that can exert a noticeable force on other materials without actually contacting them. This force is known as a magnetic force and may either attract or repel. While all known materials exert some sort of magnetic force, it is so small in most materials that it is not [...]

  • History of Permanent Magnets

History of Permanent Magnets

History of Permanent Magnets Lodestones The history of permanent magnets goes back to ancient times. Records from early Greek, Roman and Chinese civilisations make reference to rare and mysterious stones called lodestones. These lodestones could attract each other and also small pieces of iron. When suspended from a thread it was noted that they always [...]

How to Choose the Bushless Motor Magnets?

How to Choose the Bushless Motor Magnets? After you choose the slots and poles, you need to choose the magnets. This is not very easy task because you need high temperature magnets and are not so cheap and easy to find for your needed size. I bought custom made magnets from a Chinese SUPPLIER MPCO [...]
