Operating Point, Load Line and Permeability Pc of Permanent Magnet The permanent magnet works in the open circuit state. Since the magnet in the open circuit state is under the action of the demagnetization field, the magnetic induction intensity of the permanent magnet in the working state is not at the Br point in the [...]
Anisotropy of Permanent Magnet Shape and Demagnetization Field and Demagnetization Factor Make the permanent magnet into a certain shape. Take the block magnet in the following figure as an example. If you measure the magnetization curve in the open circuit state along the x, y, and z directions of the magnet, you can find that [...]

How can it be regarded as a valuable strong magnet, and how to distinguish Now many people know that strong magnet is more valuable, but they are not very clear about what kind of strong magnet is, because there are many kinds of magnets, and some people ask whether it is strong magnet if the [...]
If a magnet keeps doing work, will its magnetism be weakened or even disappear? There are many misconceptions about magnets and how they are magnetic. Since the magnetism of a magnet is invisible and intangible, it will be more abstract in the eyes of many people, and it is difficult to reflect it intuitively. First [...]
Magnetic Domains In ferromagnetic materials, smaller groups of atoms band together into areas called domains, in which all the electrons have the same magnetic orientation. That's why you can magnetize them. See how it works in this tutorial. Electrons are teeny tiny magnets. They have a north and a south pole and spin around an [...]
How are magnets made? More than 20 years of doubts have finally been solved Magnets, we remember deeply when we were young, it is a magical thing. After class, I played a magnet fight in the classroom. Two magnetic fighters each took a magnet and placed it on both sides of the center line at [...]
A girl swallowed toy magnet by mistake, and the doctor took it out smoothly 10 days ago, a 7-year-old girl Jiajia (pseudonym) accidentally put 2 toy magnets into her esophagus while playing with her classmates, and then she vomited and cried uneasy. , and then went to the Second Department of General Surgery of our [...]
Doctor, the child eat magnet, what should I do? "Doctor, the child has eaten the magnet, what should I do?" On the morning of May 18, a mother and child came to the Hengjie Town Health Center in Haishu District of Ningbo City. The 7-year-old child accidentally swallowed the magnet. It turned out that the [...]
What to do if you swallow a magnet If the magnet is swallowed in the stomach, if the general condition is good and there are no related symptoms, it can be temporarily observed; if it cannot be discharged, cathartics can be taken orally, or the foreign body can be removed directly under the endoscope. 1. [...]
Why can't small magnets be put together with big magnets? There is no such requirement, that is to say, this statement is wrong. Farewell and small magnets can be stored together. During their storage, the magnetic attraction force of the large magnet will not be separated from that of the small magnet. The weakening of [...]
Magnetic Strength and Pull Force of 3mm Dia Neodymium Magnet 3mm diameter magnets are also small magnets commonly used in shopping malls, usually made of neodymium magnets, because if you change other materials, magnetic is not strong enough. The commonly used specifications are 3x1mm, 3x1.5mm, 3x2mm, 3x3mm, 3x4mm, D3x5mm, etc. Precision electronics, handicrafts, packaging handbags, [...]
Tiny NdFeB Magnets in Smartphones and Personal Electronics Small Tiny NdFeB Magnets in Smartphones Neodymium (NdFeB) magnets are an invisible part of every smart phone. These tiny magnets are critical to the function of the phone, working quietly behind the scenes inside the phone case. These internal magnets are typically used in the speaker, receiver, [...]
Selecting the Right Electromagnet There are many variables that must be considered in the selection of a proper magnet. To help you get the best magnet for your application, we should have the following information: Surface of the Work Is it scaly, rough, flat, machined or of irregular shape? Size of the Work Give thickness, [...]

Storage Methods of Neodymium Magnet Magnets, known for iron attracting, are spontaneously strong in magnetism, no matter they are natural-made or man-made. The storage of the magnet is an important field for us to know. Below are some points. For strong magnets, neodymium iron boron magnets in this case, there are several things to look [...]
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 [...]
Meet the Smart Magnets That Hold Your 2-in-1 Together Smart Magnets in LAS VEGAS — You probably haven’t heard of Polymagnets, but if you’ve laid hands on one of today’s detachable 2-in-1s, there’s a good chance you’ve used them. The product of Correlated Mangetics Research (CMR), these “smart” magnets use complex patterns to provide just [...]
LAMINATED MAGNET ASSEMBLY LAMINATED MAGNET ASSEMBLY is to cut the whole magnet into many small pieces of magnet, and then use specific glue to bond together. These small magnets are insulated from each other and enable to cut down electromagnetic eddy current. When the permanent magnet motor is running, the motor will generate harmonic and [...]
