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 [...]
Magnet Myths Every time you use a computer, you're using magnets. If your home has a doorbell, it probably uses an electromagnet to drive a noisemaker. Magnets are also vital components in CRT televisions, speakers, microphones, generators, transformers, electric motors, burglar alarms, cassette tapes, compasses and car speedometers. In addition to their practical uses, magnets [...]
Why Magnets Stick If you've read How Electromagnets Work, you know that an electrical current moving through a wire creates a magnetic field. Moving electrical charges are responsible for the magnetic field in permanent magnets as well. But a magnet's field doesn't come from a large current traveling through a wire — it comes from [...]
The Details of Making Magnets To make a permanent magnet, all you have to do is encourage the magnetic domains in a piece of metal to point in the same direction. That's what happens when you rub a needle with a magnet — the exposure to the magnetic field encourages the domains to align. Other [...]
The Basics of Making Magnets Many of today's electronic devices require magnets to function. This reliance on magnets is relatively recent, primarily because most modern devices require magnets that are stronger than the ones found in nature. Lodestone, a form of magnetite, is the strongest naturally occurring magnet. It can attract small objects, like paper [...]
Magnetics for Environmental Applications Magnetics, as related to the environmental field, is a technology used for locating subsurface iron, nickel, cobalt and their alloys which are typically referred to as ferrous materials. The theory of magnetics has been adapted to specialized tools called magnetometers which are capable of measuring ambient magnetic fields emanating from terrestrial [...]
