1800 After History of Magnetism and Electricity

1800 After History of Magnetism and Electricity 1820 - Electromagnetism, Current In 1820, a physicist Hans Christian Oersted, learned that a current flowing through a wire would move a compass needle placed beside it. This showed that an electric current produced a magnetic field. Andre Marie Ampere, a French mathematician who devoted himself to the [...]

Before 1800 History of Magnetism and Electricity

Before 1800 History of Magnetism and Electricity 600 BC - Lodestone The magnetic properties of natural ferric ferrite (Fe3O4) stones (lodestones) were described by Greek philosophers. 600 BC - Electric Charge Amber is a yellowish, translucent mineral. As early as 600 BC the Greek philosopher, Aristophanes was aware of its peculiar property: when rubbed with [...]

Due to an early lack of standardization in the science of magnetism, we have been plagued with no less than three complete systems of measurement [...]

Permanent Magnets Magnetism and Electromagnetism

Permanent Magnets Magnetism and Electromagnetism Centuries ago, it was discovered that certain types of mineral rock possessed unusual properties of attraction to the metal iron. One particular mineral, called lodestone, or magnetite, is found mentioned in very old historical records (about 2500 years ago in Europe, and much earlier in the Far East) as a [...]

What is A Magnet Rotor Made of Magnetic Assemblies

What is A Magnet Rotor Made of Magnetic Assemblies Magnetic motor rotor is formed by magnetic steel, metal shaft or metal shell. According to detailed application situation, the rotor magnet can be sintered, molded or injection molded with NdFeB magnet material and Ferrite magnet material with multi-poles magnetic rings. It can be used for the [...]

Basic Knowledge Of Magnetic Materials

Basic Knowledge Of Magnetic Materials About Magnetic Materials: Magnetism is one of the fundamental properties of matter. Magnetic phenomena are associated with various forms of charge motion. Magnetic fields are generated by the motion and spin of electrons within a material. All matter is magnetic. According to the magnetic nature of the difference can be [...]

Motor Permanent Magnet

Motor Permanent Magnet Permanent magnet motors use permanent magnets to generate the magnetic field of the motor, without the need for excitation coils or excitation current. Compared with traditional electric excitation motors, it has significant advantages such as high efficiency and simple structure. The applications of permanent magnet motors are extremely wide, covering almost every [...]

Consequences of Residual Magnetism in Lifting Magnets

Consequences of Residual Magnetism in Lifting Magnets HSMAG’s permanent lifting magnets are designed and manufactured with minimum to no residual magnetism in lifting magnets at their OFF position. It is an important property that buyers need to consider when selecting lifting magnets. In this blog, we shall discuss what cause residual magnetism and what are [...]

Two Advantages of Electromagnet Over Permanent Magnet

Two Advantages of Electromagnet Over Permanent Magnet Magnets come in two main types: permanent magnets and electromagnets. As its name suggests, a permanent magnet is always magnetized -- think of a kitchen magnet that stays stuck to a refrigerator door for years. An electromagnet is different; its magnetism works only when powered by electricity. Although [...]

Curie Temperature of Permanent Magnets

Curie Temperature of Permanent Magnets Regarding the Curie temperature of permanent magnets, many people will ask whether the Curie temperature of magnets is the highest working temperature of magnets. We Baidu this sentence, found that there are two distinct replies, one is a positive response, the other is the opposite, then in the end Curie [...]
