Novel Magnetic Material Discovered in Meteorite Tens of thousands of tons of meteorites fall to Earth every year. Meteorites first came into existence 4.6 billion years ago and since then they have existed in space without changing their form like “fossils” in the solar system. Research on the history of the solar system has been [...]
The Neodymium Magnet Origin In ordinary life, magnets are a very common thing. And thousands of years ago, the working people in our country made the compass, one of the four great inventions, based on the characteristics of magnets. Until today, magnets are also very useful. From all kinds of special electronic equipment to the [...]
How Does Temperature Affect Different Magnets? The relationship between magnetic strength and ambient temperature is somewhat complicated. If you are in need of a magnet, however, it is important for you to understand how temperatures affect the strength of different types of magnets before choosing a product. This will allow you to choose the magnet [...]
The New Magnetic Material Possibilities Prof Schuller presented his groundbreaking finding at the American Physical Society meeting conducted in Denver. It is a magnetic sensitive material, which can alter the use of hard disks, Halbach array and storage devices. He has created a metal bilayer, using thin layers of nickel with vanadium oxide and the [...]
How does Magnetism Affect a Watch? Watches can be adversely affected by magnetism and may gain or lose time. It is important not to leave a watch close to magnetic objects for a long periods. In particular, cell phones, television and PC speakers, magnetic necklaces, handbag clasps, hair-driers, electric razors, magnetic parts of refrigerators are [...]
Permanent Magnets And Magnetic Behaviour Studying The Behavior Of Permanent Magnets Magnetic field is produced by objects known as magnets. When these properties of magnetism are not lost throughout time it’s known as a permanent magnet. So what is this special property in a permanent magnet that is not lost in the test of time? [...]
The difference between electromagnet and permanent magnet Electromagnets (solenoids) is a kind of electromagnetic equipment, which transforms electric energy into magnetic energy, and then transforms magnetic energy into kinetic energy (electric energy → magnetic energy → kinetic energy). First of all, the core is wound with a conductive winding matching its power. Such a coil [...]
Why does the bonded NdFeB magnet break after it breaks? The rectangular bonded NdFeB magnet has N and S poles at its ends. If it is broken into left and right, then does its polarity become N and S poles and S pole and N pole? Why does the bonded NdFeB magnet break after [...]
Who Discovered Magnets and Other Rare Facts We all know that magnets attract iron particles. We have seen fridge magnets, other decorative articles, and even some toys that use magnets. We have heard of the applications of magnetism in daily life. But have we thought of who must have discovered magnets and when? Who [...]
About Magnetic Webcam Cover, Protect Safe Block Your Webcams with These Magnetic Covers Magnetic Webcam cover can be divided to the plastic type and magnetic type according to the material, and magnetic webcam cover is more popular because of its more attractive texture. Magnetic webcam cover is a piece of metal which can be attached [...]
Hard Magnetic Materials Magnetic materials can produce magnetic fields, which generate forces attracting or repelling ferromagnetic materials and other magnets. Magnetic material can be divided into soft and hard magnets. Soft magnets are those materials easy to magnetize and demagnetize, while hard magnets are difficult to do so and retain strong magnetism after the removal [...]
How to Make Magnets Stronger Certain consumer products require magnetism to work properly; refrigerator magnets, some earrings, speakers, and so on. Magnets in each of these products require a strong magnetic field in order to attract and hold onto their respective objects. When these magnets become weak, they fail at their designated tasks. If that [...]
