How inductive sensors work Inductive sensors are often used to measure position or velocity, especially in harsh environments. The terminology and technology of inductive position sensors can be confusing for many engineers. In this article, the various types of inductive sensors are explained, how they work, and their respective strengths and weaknesses. Inductive position and [...]
Efficient use of weak magnetic energy, new collectors help IoT sensors "self-generate" CHINA's "dual-carbon" strategy advocates a green, environmentally friendly, and low-carbon lifestyle, which depends on the continuous development and innovation of green energy technologies. At the moment when our country is vigorously developing renewable energy, the recovery and reuse of micro-energy such as magnetic [...]
Gold, silver, copper, and iron are all metals. Why do magnets only attract iron? It is a well-known phenomenon that a magnet will attract iron. I believe that everyone has tried to use a magnet to approach other metals to see if the magnet can attract them. However, the "experimental results" are often disappointing. Because [...]
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 [...]
