Strong magnet material

Mainly, the remaining magnetic, stubborn power and maximum magnetic energy accumulation. The following is only for reference Iron magnetic material, as the latest result of the development of rare earth permanent magnet materials, is called "magnetic king" due to its excellent magnetic properties.The magnetic material of 料 iron boron is alloy of 钕, iron oxide, etc. Also known as magnetic steel. Iron boron magnetic materials are: N30 ~ N52; 30H ～ 50h; 30SH ～ 50SH; 28UH ～ 40UH; 30EH ～ 35eh, etc.It is currently commonly used high magnetic magnets. Decided by the crystal structure.Introduction: The third -generation rare earth permanent magnetic 钕 iron boron is the most powerful permanent magnet in contemporary magnets. Its BHMAX value is 5-12 times that of iron oxygen magnets, 3-10 times that of aluminum nickel cobalt magnets; its stubborn force is equivalent to 5-10 times of iron oxygen magnets, 5-aluminum nickel cobalt magnet 15 times, its potential magnetic properties are extremely hig

Electromagnet classification

Divide by current1. AC electromagnet2. DC electromagnetDivide1. Dynamic electromagnet: mechanical braking for electrical motors in electrical transmission devices to achieve the purpose of accurate and fast parking. Common models are MZD1 (single phase), MZS1 (three phases) series.2. Raidering electromagnet: used as a lifting device to hang magnetic materials such as steel, iron sand, etc., or used as an electromagnetic robot hand holding steel and other magnetic materials.3. Electromagnetic valve: use magnetic force to promote the magnetic valve to achieve the purpose of opening, closing or deduction.4. Traction electromagnet: Mainly use traction mechanical devices to perform automatic control tasks.

Electromagnetic advantage

The magnetic field direction of the electromagnet can be judged with ampel.Ampere is the rules of the relationship between the magnetic lines of the magnetic field that stimulates the magnetic field of the current and the current, which is also called the right hand spiral.(1) The Ampere Ding (Apeging Zezhi 1) in the power -powered straight wire: Hold the power -powered straight wire with the right hand and let the thumb finger in the direction of the current, then the finger of the four fingers is the surrounding direction of the magnetic line.(2) The Ampel of the Apen in the tube of the power screw line (Ampere Dingzhi 2): Use the right hand to hold the power screw wire tube to make the four -finger bending consistent with the current direction. Then the end of the thumb refers to Nary.There are many advantages of electromagnets: whether the magnetism of the electromagnet can be controlled by traffic and disconnection; the size of the magnetism can be controlled by the strength of th

Electromagnet

Electromagnetic is a device that generates electromagnetic electromagnetic. The conductive winding that matches its power in the outer winding of the iron core. This coil with a current -owned current is magnetic like magnets. It is also called Electromagnet. We usually make it into strips or hoof shapes to make the iron core easier to magnetic. In addition, in order to make the electromagnetic disconnection immediately demagnetize, we often use the fast -moving soft iron or silicon steel material to make it. Such an electromagnetic magnet is magnetic when powering, and the magnetic magnetic disappears after power off. Electromagnetic magnets are extremely widely used in our daily life, and because its invention also greatly improves the power of the generator.Electromagnetic is a device that generates electromagnetic electromagnetic. The conductive winding that matches its power in the outer winding of the iron core. This coil with a current -owned current is magnetic like magnets. It

Electromagnet principle

When the iron core is inserted inside the power thread tube, the iron core is magnetized by the magnetic field of the power pipe tube. The magnetic core after magnetization has also become a magnet, so that the two magnetic fields are superimposed, which greatly enhances the magneticity of the thread tube. In order to make the electromagnet magnetic more magnetic, the iron core is usually made into a hoof shape. However, pay attention to the opposite of the coil on the hoof -shaped core, on one side, and the other side must be clockwise. If the two coils are performed to the iron core, the magnetization of the two coils will offset each other, causing the iron core to be not magnetic. In addition, the core of the electromagnetic iron is made of soft iron, and it cannot be made of steel. Otherwise, once the steel is magnetized, it will maintain magneticity for a long time and not be magnetic, then the strength of its magnetism cannot be controlled with the size of the current, and the a
